After Replacing The Piston Trimmer Does Not Start

Petrol trimmer won’t start? Reasons and solutions for the example of Elitech T750 The gasoline garden trimmer is a simple tool at first glance, because it contains a minimum number of components and is easy to use. But

Petrol trimmer won’t start? Elitech T750 Reasons and Solutions

In general, such a conversation should start with the fact that after buying a garden gasoline tool, it would be better to first familiarize yourself with the instructions attached to it. Then many problems could be avoided. But since this happened, the gasoline trimmer will not start, then you need to look for sources of inoperability. And in this article we will look at the main reasons why the trimmer does not start on the example of the Elitech T750 model, as well as give general recommendations for using such a tool.

You should start with the banal! Let’s figure out how to properly start the gasoline trimmer. It may be that the reason lies precisely here.

First you need to bring the red toggle switch on the trim bar to position I. This means turning on the power. Then you need to switch the fuel supply lever on the carburetor and use the fuel suction button (similar to a pipette, located on the carburetor). This is necessary to supply gasoline to the engine. Return the fuel delivery lever to its original position. Finally, pull the starter handle sharply towards you. The trimmer should work. Try it several times if it doesn’t work the first time. If after such manipulations the situation has not changed and the gasoline trimmer does not start, then you should first inspect it yourself before you take it to the service center. There are two main reasons your garden trimmer won’t start:

Disruption of the power supply circuit.
No fuel.

Let’s start with the ignition problems. In most cases, it is caused by the need to change the spark plug in the engine. This is done like this:
First of all, we must take care of the safety measures, making sure the trimmer is disabled. We bring the above toggle switch to the STOP position.
Then remove the rubber cover from the spark plug and the wiring terminal. Using a special spark plug wrench, we unscrew the spark plug and replace it.
After that, we assemble the device and carry out the above procedure for starting the trimmer.

The second reason why the garden tool does not work is out of fuel. On the Elinech T750, the fuel tank is located near the engine, but on most trimmers it is located there. We unscrew the cap from the tank and fill it with gasoline (the most optimal version of AI-92, it is inexpensive and does not clog the carburetor like the AI-76). Do not forget to add a special oil for engines to the tank, 50 grams is enough for the gas tank, without it the engine will start to sneeze and quickly become unusable. Then we close the tank with a cap, wipe the trimmer surface and our hands with a dry cloth. We also do the above manipulations to turn on the garden tool.

If the petrol trimmer still won’t start, then it makes sense to have it repaired. And the reason for such a decision is simple, if you do not have the appropriate skills, equipment repair is almost impossible.

In order for the tool to serve as long as possible and not to have such problems, you should first of all read the instruction manual for the trimmer. Also, pay special attention to the engine running time at the trimmer, take a short break every 15 minutes of work and, finally, take proper care of the tool, wipe it after work, lubricate with graphite grease. Observing such simple rules, you can significantly increase the service life of the tool and it is quite possible that you do not have to look for reasons why the gasoline trimmer does not start.

Trimmer won’t start after winter

How to be in such a situation? Don’t worry and panic. This is a very common problem that can be solved in just 3-4 minutes. Firstly, if last year’s fuel remains in the gas tank, then it must be drained. Gasoline loses its octave properties after 2 weeks of inactivity. Secondly, you need to start a petrol cutter after a long stagnation in a slightly different way. First you need to open the throttle and pump a little fuel mixture into the carburetor, then pull the handle until you feel a little resistance. Then you can start the trimmer.

Trimmer won’t start. Why?

A petrol trimmer is an amazingly useful thing that can be used to tidy up not only a miniature lawn in the backyard of the house, but also mow a lawn of considerable size without any extra hassle. But, like all things in this world, it tends to break. In this article, we will try to figure out what to do in cases where the trimmer refuses to work.

Petrol trimmer won’t start well

So what to do if the petrol trimmer won’t start well or won’t start at all? The most common reason for such a breakdown is poor quality fuel. Remember that, for example, trimmers of the Stihl and Husqvarna brands are unlikely to start on fuel quality lower than AI-92. You should not save on fuel, because repair of parts of the cylinder-piston group can be one third of the total cost of the scythe, and sometimes even half. Also, when preparing the fuel mixture, it is necessary to correctly observe the proportions of fuel and oil, which are always indicated in the instructions for the trimmer.

What to do if high-quality fuel is poured into the gas tank, there is a spark, but the tool still refuses to start? It is necessary to check the condition of the candle. It is located in the center of the mower body. It must be carefully unscrewed and make sure there is no plaque on it. If there is, then carefully clean the candle from carbon deposits and dry it.

If the brushcutter does not start even after the methods suggested above, then you need to try to remove the air filter and start the device without it. If the trimmer still doesn’t work, dust off the old filter or buy a new one.

It also happens that the mower works for a maximum of 5 minutes, and then stalls and does not start until it cools down. In this case, try to open the filler cap of the gasoline filler cap; a suction sound should appear. Then screw the cap back on. If you do this manipulation while the trimmer has just started to stall, then the speed will be restored, and you can continue to work. If the mower stalls before opening the lid, then you just need to start it as expected according to the instructions.

Trimmer starts and stalls

If, when trying to start the trimmer, it starts, but immediately stalls, then the air filter may again be the reason for this. It is necessary to remove it and check if it is clogged with dust. If this is true, then you need to thoroughly clean it or purchase a new one. Also, the problem may lie in the malfunction of the ignition coil. In this case, take the mower to a service center.

After replacing the timing belt, the car will not start? Several reasons why

Sometimes it happens that after replacing the timing, the car does not start. The problem can occur on various vehicles. Over, it can manifest itself on a variety of models. The reasons in any case will be approximately the same. It is advisable to eliminate them immediately after identification. To do this, it is worth knowing all the options for malfunctions that prevent the engine from starting. In principle, there are not so many of them. It is also important to correctly change the timing drive (gas distribution mechanism).

Any mistake can lead to subsequent problems. Before checking the timing drive, be sure to check the condition of the ignition system, the battery. The reason may be this.

After Replacing The Piston Trimmer Does Not Start

Cliff problems

After replacing the timing, the car will not start. If this problem occurs after the timing belt breaks, then the cause must be sought in this. If the drive is broken, the valve timing is lost. Most often, the collision of pistons and valves occurs. This ends, at best, with bending of the valves, at worst with damage to the pistons.

Many manufacturers at one time made pistons with this danger in mind. They have special valve recesses on the upper surface of the pistons. Such engines can be seen on VAZ 2108, 2109. Also, some cars of the tenth family were equipped with similar motors. From foreign cars, such pistons can be found on some Mitsubishi, Renault and some other brands. But only on fairly old cars.

It turned out that such grooves significantly reduce engine power.

There are two ways to identify a valve problem:

Remove the valve cover and carefully turn the engine over. At the same time, carefully monitor the operation of the valves. If one does not work, then most likely it is bent. This method is not reliable, in many cases the valves will work as expected;
A more reliable way is to study the state of the valves directly on the removed head. All bent valves are visible to the naked eye.

An article on the topic “On what engines does the VAZ not bend the valve”.

If you determine that the valves are still damaged, then you will have to replace them. This must be done in full. Remember to grind new parts normally.

Incorrect replacement

Often, a problem with engine cranking occurs during a scheduled belt replacement. This is mainly due to the wrong assembly. In this case, the phases do not match. In practice, it turns out that the compression stroke ends in one cylinder, and the spark hits the other. Therefore, it is important to do the replacement carefully and thoroughly.

The mismatch of marks on the pulleys is a fairly common mistake of novice mechanics. Many people forget to deduce the engine on them. As a result, the spark cannot meet the piston. Be sure to check the position of the marks. Remember that the crankshaft speed is different from that of the camshaft. To accurately determine the conclusion of the fourth cylinder at top dead center, you should unscrew all the candles.

A rubber stopper is inserted into the fourth cylinder; instead, you can take a disposable plastic bag, they also clog the hole for the candle. When the engine shoots off the plug, the cylinder is just near the dead center of the compression stroke.

It remains to bring it up a little, checking the position with a screwdriver. After that, the position of the marks is checked. The bottom will naturally match. Well, unless, of course, you did not touch the crankshaft. So pay attention to the top one. If it does not match, then this is the reason. Take off the belt and take out the camshaft pulley along the marks. Then install the belt and try to start the engine. Most likely, it will start.

Also on some models there is a mark on the flywheel. Few know about it. But it must also match. Often the reason for the engine not starting after replacing the timing is precisely this. Keep in mind that the flywheel is often dirty, and it can be quite difficult to see the mark there. Therefore, be careful.

On carburetor engines, ignition may be lost when the belt is replaced. Precisely, the compression stroke moves from the fourth cylinder to the first. This is a sign of an unqualified build. You should adjust everything according to the marks again. If right now you need to go, it happens, then you can swap the high-voltage wires of the fourth and first cylinders. This will help you start your car without any problems.

Details. Some drivers, trying to save money, do not buy new videos. In this case, the installed belt simply slips and the car will not start. The same problem can happen with the wrong selection of components. Always purchase only belts and rollers recommended by the manufacturer. Also, the timing drive must be changed entirely, partial replacement can lead to damage.

Conclusion. Replacing the drive of the gas distribution mechanism is a rather complicated and responsible procedure. Even with experienced mechanics, it can happen that after replacing the timing, the car will not start. If beginners get down to business, then this is generally an ordinary phenomenon. In this regard, carefully study the rules for replacing the drive, as well as all possible causes of further malfunctions.

We carry out diagnostics of a candle and a candle channel

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

We unscrew the candle and wipe it;
Dry it thoroughly (do not ignite);
We drain the excess fuel in the chamber 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 expose a gap with a distance of 1 mm (you can check with any coin);
We put everything back in place and try to start the trimmer.

If the candle is working, the socket where it is located is completely dry, and the petrol cutter does not want to start, lubricate the threaded connection with gasoline. It should be slightly damp. No matter how wonderful a spark the candle may give out, there is simply nothing to ignite 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 poor contact between the spark plugs and the high-voltage wire. If the connection is good and there is still no spark, most likely your ignition unit has flown. Here it will not be possible to do without a master, since the part is not repaired, but sold as a single unit.

Why the petrol cutter won’t start troubleshooting

Caring for the personal plot, summer residents periodically encounter the fact that the petrol cutter 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 individual parts.

How to start diagnostics of brushcutters

If the brushcutter 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;
Outlet channel.

These nodes are most often the source of major problems that can be eliminated after a thorough inspection.

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 do not be clever 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). Prepare the oil-fuel mixture strictly according to the instructions. Calculate its amount based on real needs. Excess gasoline left over after work loses its quality over time.

Breather and exhaust port

Often, delicate branded petrol brushes do 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. You can eliminate the malfunction 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 dirt entering the exhaust channel or a clogged silencer 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.

Diagnostics of filters for petrol cutters

Another reason why the gasoline scythe stalls is the air filter. To eliminate it, try removing the filter and starting the trimmer without it. If possible, then you will have to change the air filter to a new one, or at least blow through and thoroughly clean the old one.

The petrol trimmer may not start if the fuel filter is dirty. 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 pipe completely without a filter, this is prohibited by any operating instructions. Haste can turn into repairing the engine piston group.

Perform cold starts correctly!

Often, gasoline trimmers do not start after trying to put them into operation after long-term storage. Launch failures in this case are often caused by incorrect user actions.

If you are faced with this very phenomenon, then during a cold start you need to close the damper, and then pump a small amount of the fuel mixture into the carburetor. Then pull the starter handle until you feel resistance, then start the trimmer with sharp and energetic movements.

The main thing. Fuel mixture!

In this case, the remnants of plastic dissolved in an aggressive environment do such terrible things in the combustion chamber that you will definitely not be able to do without completely sorting out the mechanism. But you will certainly remember forever how to properly store fuel.

What to do when the fuel was definitely normal, there is a spark, but the petrol trimmer will not start? It is possible that you just filled the candle with gasoline. In this case, it must be turned out, wiped with a clean cloth and dried. By the way, it will be quite useful to check the candle itself for performance.

What to do when the petrol trimmers won’t start?

The petrol trimmer is a surprisingly useful tool that can be used to mow not only a miniature front lawn, but a whole lawn of considerable size. Unfortunately, there is nothing eternal in this world, and therefore you may be faced with the fact that petrol trimmers do not start.

It often happens that users of this kind of cars are trying to save money by filling the tank with not fuel with a normal octane number, but something incomprehensible that has been in a plastic canister for almost a dozen years.

Reasons

There are not only situations when petrol trimmers do not start, but there are cases when, after starting, they work for a couple of seconds and immediately stall. Inspect the spark plug again: if it is thrown over, and this situation repeats even after wiping and drying it, proceed to revising the air filter.

Most likely, it is completely oiled and needs to be replaced. If everything is normal with the filter, it may be that the ignition coil is out of order.

In the case when the petrol trimmers do not start, and you have done all of the above, the muffler may be clogged. It must be dismantled, burned on a burner, after which all carbon deposits can be easily shaken out.

Even if your trimmer will not start even after such bullying, you cannot do without disassembling the carburetor. It may very well be that the falling needle in it is to blame for everything. In any case, disassembling and flushing this whimsical mechanism will certainly not interfere.

In general, when the trimmer began to be capricious and stall, it is advisable to carry out full prevention: completely change the fuel mixture, try a different oil, and also change the spark plug without fail. Practice shows that in many cases it is cheap poor-quality candles that are to blame.

We’ve covered the most common reasons why the trimmer won’t start. If the matter is in something more exotic, you cannot avoid going to the service center. You will probably find smaller and more obvious breakdowns yourself.
