The Lawn Mower Will Not Start On A Cold

the lawn mower starts and stalls. What to do?

There is a spark, and everything seems to be normal, but the lawn mower will not start, in such cases you should check the air inlet valve to the fuel tank. A clogged valve leads to the creation of a vacuum in the tank, in which the carburetor does not receive enough gasoline, so the lawn mower will start, but then stall. To exclude this reason, you need to clean the valve and try to start the lawn mower C with an incompletely twisted tank cap.
2. If the lawn mower does not start at the same time, remove and clean the fuel filter, as well as check all carburetor parts, and then try to start. Again The lawn mower will not start, the air filter is disconnected, try to start without it, if the mower starts, then the reason is in the air filter, replace it.

lawn mower Will not start on a cold

When starting a cold engine, it is not recommended to press the gas. Tilting the mower so that the air filter is on top, press the fuel suction button 5-6 times, set the function switch lever to the “start” position, pull the cord several times until the engine starts. After a few seconds of engine running, disable the starting system.

The lawn mower will not start, or will start but stalls. What is the reason?

To understand this, you need to know the principle of operation of the unit as a whole. It also happens that a new saw just bought does not start, and it starts running around the service centers, in such cases it is recommended:

Read the instruction manual carefully;
study in detail the method of first starting and running in lawn mowers;
try to understand how the product works;
how is pumping gasoline and so on.

Causes of malfunctioning lawn mowers:

The quality of the gasoline is poor;
incorrect proportion of gasoline and oil;
clogging of the fine filter;
the spark was gone.

lawn mower Will not start after winter

In such cases, the unit must be serviced. Remove the fuel system, including filters (air, fuel), disassemble the carburetor, clean and rinse each unit. Blow out the filters with air. Pay attention to fuel quality and octane number.

It should be noted that the products of such well-known companies as STIHL, Husgvarna and other brands will not work on cheap gasoline with a low octane number.
For them, fuel from the AI ​​brand. 92 and above is suitable from automobile gas stations and then from well-recommended ones, since there is also bad gasoline at gas stations. Here are the applications of high-octane and high-quality gasoline, it will depend on how long the lawn mower will be used and how long it will last.

It is necessary to take into account one more fact that with a long storage of a diluted fuel mixture, working qualities fall into it, which also leads to the consequences in which the lawn mower does not start. Therefore, it should be diluted in portions, that is, the amount of mixture that is produced at a time.
The operating instructions clearly describe and explain the mixing ratio of gasoline and oil. Strict observance of the correct proportions will at least save you from several questions, why the lawn mower does not start and what to do in such cases.

lawn mower Will not start, spark has disappeared

The loss of a spark entails checking the contacts and the correctness of the gap between them, the conducting wire to the candle and the candle itself.
Spark check method. Unscrew the spark plug, connect a wire to it, put the spark plug sideways to the engine casing and pull the starter several times as if Starting the lawn mower, while looking at the Coal and the spark plug contact, there should be a spark between them.
If there are sparks, take a new candle, do the same procedure, if the spark is NOT traced, then the problem is in the wire or contacts, it is better to replace them.

lawn mower Will not start when hot

If the mower was recently in operation and has not yet had time to cool down but does not want to start. press the gas trigger, pull the cord sharply several times, until the engine starts and only then the gas trigger is released. If enough time has passed and the lawn mower has cooled down, then it should start as if it were cold.
If the above methods did not help, the lawn mower did not start, then you should contact the service center.

Ignition coil

The reason that a new chainsaw does NOT start, or does not start well, may be the ignition coil. Modern chainsaws are equipped with electronic ignition coils. This part cannot be repaired, and, as a rule, if there is a defect, it changes completely.

The gap between the ignition coil and the flywheel

An incorrectly set gap between the flywheel and the contacts of the ignition coil affects the quality of sparking, which in turn is responsible for normal start-up and stable operation of the engine.

Chainsaw stalled and will NOT start

If the tool stalled and does not start, first check the presence of fuel in the tank. Oddly enough it sounds, but many people forget about it and when such a situation arises, they immediately try to repair the instrument, which can lead to serious damage.

In a situation where the saw has stalled, and there is still gas in the tank, you need to evaluate how the saw worked up to this point. Maybe at the last moment there was an extraneous sound, grinding, ringing, power loss, or the instrument stopped abruptly. All this will allow a preliminary assessment of the situation.

Carburetor adjustment

NOT correct carburetor adjustment will be a prerequisite for the chainsaw to develop at full power. It will not start well, or will not start at all. The carburetor setting directly affects the quality of the air-fuel mixture, which is necessary for normal starting and further engine operation.

An excess of gasoline in the mixture is called overflow. A characteristic sign of overflow is a wet spark plug, after several unsuccessful attempts to start the chainsaw.


Overheating of the engine during operation may cause the saw to stall and will NOT start. Overheating is dangerous enough, as it can cause the piston to melt in the cylinder and the engine to jam. At the first cases of overheating, it is worth diagnosing the tool for the presence of extraneous air suction into the engine, and adjusting the carburetor.

Air leaks, as well as incorrect carburetor adjustment affect the maximum number of engine revolutions and its lubrication, which in turn causes overheating and jamming of the tool.

Reduced compression

One of the frequent cases of difficult starting of a chainsaw is wear of the CPG (cylinder-piston group).

As you know, for the normal start of a chainsaw, compression must be present in its engine. It is necessary for the normal compression of the fuel mixture in the engine cylinder, it also affects the operation of the gas pump.

READ  Changing The Oil In The Lawn Mower Gearbox

The reasons for the absence of compression, or its reduction, may be natural, because. The engine wears out during operation. Also, problems can be caused by a serious breakdown, for example, a seizure of the CPG, or a broken piston ring.

A sign of reduced compression is a weak resistance of the starter when starting. With reduced compression, a decrease in the power of the chainsaw is observed, which negatively affects its performance. The problem is eliminated by replacing the piston rings, or completely by the CPG.

Engine jammed

Quite often, there is a situation when the saw worked and stalled abruptly, the prerequisite for which was the engine jamming, which in turn occurred as a result of a broken piston skirt, destruction of the crankshaft bearing, protruding piston pin cork rings or spilling the piston ring.

A jammed motor can be easily identified by pulling on the cord. In the case when the starter does not turn, most likely, it has jammed, and further repairs are possible only in a service center.

Broken fuel line

During the operation of the chainsaw, vibration occurs, which can cause damage or breakage of the fuel line of the chainsaw. In this case, the chainsaw will stall and it will be impossible to start. To diagnose a malfunction, you need to conduct an inspection and determine the presence of fuel leaks.

Fuel problems

As with the difficult hot start option, problems in the fuel system can affect a cold start or inability to start. Adjustment of the carburetor, contamination of the fuel filter and the line, all these are the reasons that cause difficulties when starting.

Diagnose the fuel system, this is the first thing you need if it is difficult to start on a cold.

It is worth paying attention to the quality of the fuel, because When using a mixture of gasoline and oil, in which there is a small amount of water, starting can be significantly difficult or impossible.

Adjustment and tuning of the carburetor

The maximum and minimum engine speed, smooth idle speed are regulated by the carburetor. Here are the amounts of fuel mixture and air supplied, their ratio depends on the steady operation of the lawn mower. lawn mower Will not start if the carburetor is incorrectly adjusted. The procedure for adjusting the device for supplying fuel at low speed (L), high speed (H) and idle (T) is regulated by the screws of the same name:

  • The chainsaw should run for at least 10 minutes, since the adjustment is carried out hot.
  • Screw H is turned smoothly to maximum speed, then turned by ¼, counterclockwise, reducing the speed of rotation of the engine shaft.
  • The idle speed is adjusted with the screw T, ensuring that the scythe does NOT rotate.
  • The screw L is adjusted, at first opening the maximum throttle, and then smoothly reducing the speed to stable minimum.

After adjustment, a working carburetor with cleaned filters and a checked ignition must ensure the engine is running. In the event of a carburetor malfunction, after repairing it, you will need to adjust the feed system again before starting the lawn mower.

Rare breakdowns that interfere with the operation of lawn mowers can be:

  • Rewind spring defective;
  • Broken or stuck starter pulley;
  • Defective starter assembly.

The most important malfunction, the elimination of which is associated with replacing the engine, may be the failure of the engine piston group. The cost of repairs will cost about 70% of the cost of the product. Understanding the reasons why the lawn mower won’t start will help:


All the reasons why the lawn mower does not start can be classified according to the specifics of the operation of SEPARATE units. In the service center, faults are classified:

  • Engine failure (piston wear, bearing failure, crankcase cracked)
  • Malfunction of the fuel mixture supply. clogged pores of the air filter or malfunction of the carburetor;
  • The ignition system does not work;
  • Mechanical malfunction. leaking hoses, broken braided wires, ruptured tubes.

The user first needs to check if there is fuel in the tank. The launch is carried out in accordance with the annotation, put the dust on its side. Set the air damper to the “closed” position, pump up fuel, turn on the ignition and make 3-4 sharp jerks with the starter. If the engine is running, open the air damper. The lawn mower does not start. we repeat the operations with a slightly open air damper.

the lawn mower cannot work for a long time. The gearbox and engine will overheat. Mows Can be no more than 15 = 20 minutes, taking a five-minute break. On sultry noon, the operating time is cut in half. When mowing weeds, sedges, the working time is required.

If the launch fails, we start looking for the reason for the failure:

  • Check fuel quality;
  • Make sure that the candle is working and the candle channel is clean;
  • Check the cleanliness of the air filter;
  • Make sure the fuel filter is not clogged;
  • Check the cleanliness of the breather;
  • Cleans the outlet.

complex causes will be found during the diagnosis of malfunctions leading to overhaul of the carburetor. Such reasons include clogging of the internal channels of the carburetor, wear of the gasket on it and a violation of the tightness of the internal Holloway with a loss of vacuum. Do-it-yourself lawn mowers repair, if it won’t start, will take patience.

Eliminating the reasons why the lawn mower won’t start

The fuel mixture must be prepared with the exact proportions of gasoline and oil. In this case, you must not use another brand of fuel. To exclude the ingress of dirt, gasoline must settle in glass or metal containers for 2 days. Do not use plastic utensils for storing fuel. Measure the oil accurately with a medical syringe without a needle. Use only freshly prepared mixture. Do NOT leave used fuel in the tank. If the engine is naughty, the lawn mower stalls, when you press the gas, the fuel may be to blame.

lawn mower Will not start hot. pull the gas trigger and sharply pull the cord several times until the engine starts, then pull the trigger. Will not start. specialized repair required.

Checking the ignition system, if the lawn mower does not start, is carried out sequentially:

  • The removed candle will be cleaned of carbon deposits and dirt, dried, set a gap of 1 mm;
  • Connect to the high-voltage wire and check for Spark by pulling the starter several times;
  • If there is no spark, check the high-voltage wire for integrity;
  • Replace the candle;
  • Dry the candle channel;
  • At the same time, the operation of the ignition coil is checked, it is faulty if the working plug does NOT spark.

It is in the event of a malfunction of the ignition coil of the lawn mower Does not start up hot, stalls, works intermittently.

Cleaning or replacing the air and fuel filter will ensure the proper consumption of ingredients entering the carburetor. The air filter can be washed in soapy water or replaced. If nylon is used, it is washed, the porous felt filler is replaced. Change the fuel filter carefully. Do not leave the intake port open. Whether it is necessary to replace the air filter can be determined if the engine starts with the air cleaner removed. Whether it is necessary to change the grid for fuel supply, if the lawn mower does not start, a dry candle will tell.

Breather, gas tank air inlet. If it becomes clogged, a vacuum is created in the tank and the mixture does NOT enter the carburetor. The hole can be blown out with air or cleaned with a needle. Clean the exhaust duct, remove the anti-spark screen of the muffler.

The most common reasons the lawn mower won’t start

  • Poor quality fuel. What gasoline do you fill your scythe with? STIHL and Husqvarna tools will NOT run on cheap fuel, they need fuel NOT lower than 92 RON from a reputable gas station. It is not worth saving on gasoline, since the repair of the cylinder-piston group can be a third of the cost of the tool itself. When preparing the fuel mixture, observe the proportions of fuel and oil, which are indicated in the operating manual. Please note that gasoline mixed with oil will lose its properties over time, so it must be used within two weeks. Always keep the fuel mixture fresh!
  • Fuel filter in the tank. If the lawn mower does not start, be sure to check the condition of the part. Please note that the inlet must not be left without a filter.
  • You’ve checked everything you can, but the lawnmower still won’t start? You may have forgotten about the air filter. It must be removed, and then try to run the tool without it. Starts up? This means you need to clean the old or install a new filter.

Lawn mowers start types

What needs to be done first? Press the throttle lock and the associated trigger to set the throttle to the start position. Then we press the start button. I release the throttle lock, throttle trigger and start button. Thus, we have activated the throttling function. To return the engine to idle speed, you must press the throttle lock and the throttle trigger again.

The Lawn Mower Will Not Start On A Cold

Starting a cold engine lawn mowers

Please note that you must not pull the throttle trigger before the engine starts and starts running.

  • We place the tool on a flat surface and slowly press the fuel pumping button up to 10 times, the number may vary depending on the model.
  • Then set the lever of the start system switch to the “START” position.
  • Pull the cord sharply until the engine does NOT start.
  • Let the power unit run for 5-10 seconds and then pull the throttle trigger to disengage the starting system.

Starting a warm engine lawn mowers

  • Hold the throttle trigger depressed and do not release until the engine is running smoothly.
  • We sharply pull on the cord and wait until the power unit does NOT start. The trigger in this case must be pressed.
  • A warm engine is started within 10 minutes after it has stopped. If more time has passed, then use the instructions for turning on the cold unit.

Starting the engine with a flooded spark plug

In this case, the power unit can be started by setting the starting system lever to the RUN position, the throttle trigger must be pressed. Then we pull the starter handle as many times as it takes to start the engine. If the power unit DOES NOT start for a long time, you should contact the service center for help.

lawn mower Will not start on a cold

When starting a cold engine, it is not recommended to press the gas. Tilting the mower so that the air filter is on top, press the fuel suction button 5-6 times, set the function switch lever to the “start” position, pull the cord several times until the engine starts. After a few seconds of engine running, disable the starting system.

the lawn mower does not start well when hot

When the lawn mower is working properly, and after a short break it does NOT want to start again, you need to press the gas trigger and pull the cord sharply several times in a row until the engine starts and only then release the gas trigger.

The lawn mower does not start on a hot one, stalls when you press the gas, do it yourself repair,

The tool, despite its small size, is a complex technical device. If you study the operating instructions, it turns out that the reasons why the lawn mower does not start are known and removable. It is necessary to consistently eliminate the factors that make it difficult to start the tool. Usually start with more accessible nodes with an easy health check.

The lawn mower won’t start

When caring for a garden plot, sometimes people have to deal with the fact that their lawn mower will not start. There are several reasons for the failure of this tool.

How to start diagnosing lawn mowers

If the lawn mower does not start or immediately stalls after starting, it is necessary to sequentially check all the main components and assemblies. The verification algorithm is as follows:

  • Fuel tank (fuel quality);
  • Candle and candle channel;
  • Air filter;
  • Fuel filter;
  • Breather;
  • Exhaust channel.

These nodes are most often the source of the main problems, which can be eliminated after a thorough inspection.

Breather and exhaust port

Often, “gentle” branded lawn mowers will NOT start and stall due to a dirty breather. The main function of this element is to equalize the pressure in the gas tank. When this unit becomes clogged, a vacuum is created in the tank, preventing the supply of fuel. Eliminate the problem by cleaning the breather. You can use a regular needle for cleaning.

Normal operation of streamers with internal combustion engines can be disrupted due to the ingress of dirt into the exhaust duct or clogging of the muffler mesh. There is such a problem on older generation models. The issue can be resolved by traditional cleaning and removal of the anti-spark grid.

complex reasons for lawn mowers failure

If the step-by-step troubleshooting algorithm does NOT work, and your scythe still does not start or stalls, it is worth inspecting the carburetor and the engine itself. A clogged carburetor can be one of the reasons for erratic tool performance. There are three main problems here:

  • Clogged ducts or nozzles. All this is cleaned by special washes or blown by a powerful jet of compressed air from the compressor. DO NOT use needles or wires as the bore may be damaged;
  • Worn carburetor gasket. Exit. replacement of a failed gasket
  • Violation of tightness. To check this indicator, you can use an ordinary household tonometer, Replacing a suitable pressure gauge on it. Watch the readings: if they do not change, everything is fine, but if the pressure starts to fall, then some part of the carburetor is faulty. We’ll have to find it and replace it with a new one.

If everything is in order with the carburetor, then the gasoline trimmer may NOT start due to wear of the piston group. Replace the piston or cylinder if chips, scratches or scuffs are found. Piston rings are subject to mandatory checks. A small LUF of the piston when the connecting rod wiggles indicates that it is time to change the rings. This procedure is best entrusted to the specialists of the service center.

Filter diagnostics for lawn mowers

Another prerequisite for stalling a gasoline scythe can be an air filter. To eliminate it, try removing the filter and starting the trimmer without it. If it works out, then you will have to change the air filter to a new one, or at least blow and thoroughly clean the old one.

The petrol trimmer may not start due to a dirty fuel filter. This is the next step in our algorithm. Here we check the condition of the filter element and, if necessary, replace it with a new one. When replacing, try NOT to leave the suction inlet without a filter at all, this is prohibited by any instruction manual. Haste can turn into repair of the engine piston group.

Checking the fuel mixture

Before starting the engine of the gasoline streamer, check the presence and quality of the fuel mixture. DO NOT save, do not be greedy and “don’t be smart ”in this matter. Repair or replacement of the piston group will cost you too much (sometimes up to 70% of the cost of a new tool). Prepares the oil-fuel mixture strictly according to the instructions. We calculate its amount based on real needs. Excess gasoline left over after work loses its quality over time.

Why The Lawn Mower Won’t Start. Troubleshooting

Caring for the personal plot, summer residents periodically encounter the fact that the lawn mower does not start. There are many reasons for tool failure. For the correct diagnosis of the problem, the owner of a useful unit in the country needs to know the device and the principle of operation of its SEPARATE parts.

We carry out diagnostics of a candle and a candle channel

If the quality of the fuel mixture is not in doubt, and the lawn mower stalls when starting, then a flooded candle may be a prerequisite. Here, an ordinary spark plug wrench is suitable for repairs (every motorist probably has) and a spare candle.

  • We unscrew the candle and wipe it;
  • Dry it thoroughly (not cost if ignited)
  • Excess fuel in the chamber Drain through the spark plug hole and dry it;
  • We clean the old candle from carbon deposits using a file or a lady’s file;
  • We set a gap with a distance of 1 mm (you can check with any coin)
  • Putting everything back in place and trying to start the trimmer.

If the candle is working, the socket where it is located is completely dry, and the lawn mower does not want to start, lubricate the threaded connection with gasoline. It should be slightly damp. No matter how wonderful a spark the candle gives out, there is simply nothing to light up in a dry chamber.

If the trimmer motor still does not start, you should exclude such a reason as the absence of a spark due to weak contact between the spark plugs and the high-voltage wire. If the connection is of good quality, but there is still no spark, most likely your ignition unit has “flown”. Here you will NOT be able to do without a master, since the part is not repaired, but sold as a single unit.

Rules for the operation and storage of lawn mowers

In order for the lawn mower to start well in the future, you need to provide it with good storage and operation conditions:

  • During operation, carefully monitor the cooling system, carefully and in time clean the channels in the housing, as well as the ribs of the starter;
  • If necessary, use solvents, kerosene and other detergents for cleaning;
  • DO NOT clean the tool “hot”. let it cool;
  • Strictly follow the instructions for the operating mode, otherwise you may overheat the engine;
  • If you do not plan to use the lawn mower in the next month, the fuel mixture must be drained from it, because Over time, it breaks down into heavy fractions, which will definitely clog the carburetor channels;
  • After draining the fuel, let the trimmer run at idle, until it stalls, this will help completely remove the remaining working mixture.

Before winter storage Proceed as follows:

  • Completely disassemble the braid, Rinse and clean all the parts you can;
  • Inspect the parts for damage, if necessary, eliminate distortions, tears, bends and any other malfunctions;
  • Fill the gearbox with sufficient oil and clean the air filter;
  • You can partially disassemble the motor, rinse, blow out and grease all moving parts;
  • In order to lubricate the piston, you need to Unscrew the spark plug, lift the piston to the dead center with the starter, pour a little oil into the plug hole and turn the crankshaft a couple of times;
  • If you are storing the lawn mower outside your home, wrap the engine with oiled rags.

Why a scooter does not start well when cold, let’s figure it out together

The four-stroke scooter is a loyal assistant for many owners, which is used at any time of the year. Therefore, you can often face a problem when the scooter does not start well on a cold one or does not want to start in winter. This is due to a number of reasons that you can eliminate yourself. Most often, the problem lies in the ignition system, the power supply system may junk, and air leaks cannot be ruled out, but this problem occurs somewhat less often. From this article you will learn how to identify and solve the problem, make the scooter start immediately and in any weather.

Malfunctions in the power supply system

The power system may be to blame; if the piston group of the engine is working properly, then it should be checked whether gasoline enters the combustion chamber or not. It is easy to check this: Unscrew the plug and inspect it, if it is wet, it means that gasoline is coming in. If it’s dry, we start checking with the gas tank: first, you need to find out if there is gasoline there. If so, check if the tap is open. If everything is open, remove the vacuum hose and clean it with air.

If everything is in order, go to the carburetor float chamber. The bottom of the device is removable, it is usually held by bolts. It contains a float. If the chamber is full, and gasoline does NOT go to the cylinder, most likely the jet is clogged. You will need to pull out the needle, remove debris, dust, all foreign particles. You can also check the scooter petal valve: it is located below the carburetor. The petals can be damaged and the scooter will not start, even if it is new. If the petals are not tight enough, the valve must be replaced. In some cases, you can adjust the petals with your fingers, but such a measure will not help for long. just to start the scooter several times and ride it for details.

In case of serious damage, the piston should be checked, whether it gives the desired compression ratio, the oil seals of the piston system, the CPG and the ignition system. But these reasons are rather characteristic of the old technique, for which it was not cared for properly.

There is spark in the spark plug

First of all, it is worth checking the candles if the moped does NOT want to start.

If there is a spark, and its color is yellow, then you need to put a new candle, yours is already of little use for use. Normal spark is blue and continuous.

If the coil is new, as are the candles, and there are sparks, it is still worth checking the following:

  • Oxidation of electrical wires contacts. They will need to be cleaned, for example, the wires going to the battery are often oxidized.
  • No spark on the wire. This means that somewhere there is a bare wire that touches an ungrounded metal part, because of this, a spark does NOT appear, since the current does not reach the coil. Check wiring.
  • The switch can also fail. This is an inexpensive part that does NOT hurt to always have in stock.

Ignition system

The entire ignition system must be checked if the spark was, and then disappeared. If the candle and coil are normal, but there is still no spark, you will have to check more thoroughly. The coil, the generator winding, the switch falls under suspicion. A multimeter can check all this: for example, they test the generator like this. one probe is connected to the engine crankcase, the second to the generator sensor.

The resistance of an intact sensor is 500 ohms. If the value is higher, the winding is faulty, if it is below 200 Ohm, the matter is in the coil.

Typical reasons

Starting a scooter in cold weather may not always work out due to various factors. First of all, do not cost tormenting equipment if it did not start immediately. Check the following:

  • Battery condition. If its charge is less than 12A, the starter will NOT work. The normal voltage should be 14.5, this can be checked with a voltmeter. Try to start the scooter with a kickstarter.
  • No spark. If the scooter worked fine, but then stopped starting, you should check if there is a spark. To do this, remove the candle and check its condition. Problem could also be coil or commutator.
  • The technician may NOT be satisfied with the quality of gasoline.
  • The malfunction may be hidden in the power system. If the scooter does not start well when cold, try adjusting the carburetor.

Checking basic systems

In order to understand why the scooter won’t start, the problem must be looked for sequentially:

  • Start with the simplest. check the battery charge, if it is normal, proceed further.
  • Check if the scooter has gas, forgetting to refuel is easy.
  • See if gasoline goes into the carburetor.
  • Unscrew the candle, inspect it and check if there is a spark.
  • If the candle is in order, check the coil as described above, turning the starter with the candle removed.
  • We check the coil and wiring with a multimeter, there may be an open circuit.
  • Clean the carburetor and adjust it correctly.

Supply system

After checking the electricians and making sure that everything is in order in it, you should get to the power system: if the fuel is supplied in the wrong amount, the scooter may not start. With a large amount of fuel, the carburetor overflows, and the plug becomes wet, and if there is little fuel, there is not enough fuel for the piston to start moving. To do this, you need to adjust the jet, floats and needle by moving the stop on it. The petrol pump also does NOT interfere with checking: sometimes it simply fails, so the fuel does NOT go anywhere.

If the scooter does not start on a cold

What else to do to start the scooter, you can find out from the following:

Conclusion: Having studied the reasons why the scooter does not start, you can calculate them yourself and eliminate them at home. If there is no serious breakdown, such as a piston failure, the repair will take a few minutes.
