Husqvarna 128r Not Gaining Speed
There are frequent cases when owners of chainsaws encounter their breakdown and it does not matter what model of this kind of equipment, since the nature of breakdowns is almost the same for everyone. Well, here’s the chainsaw stalled and what’s next? Undoubtedly, you can attribute the equipment to specialized services that will repair your “iron friend” for a fee. But as they say: why pay more?
After all, you can personally disassemble the tool and repair it, since the breakdown can be insignificant, and in the service you will pay a lot. But naturally, in order to bring the instrument back to life, you need to be able to understand the causes of its breakdown and troubleshooting methods. So let’s learn! In this article you can find answers to questions regarding situations when the tool simply stalls after directly pressing the gas. So let’s get started.
The main elements of chainsaws
Before you begin to delve into issues of breakdowns and repair of the tool, let’s first figure out what the chainsaw itself consists of. First of all, I would like to note that this tool belongs to the category of technology, the operation of which directly depends on the internal combustion engine.
It is also important that chainsaws are equipped with a single cylinder engine, and whose work is carried out on such kind of fuel as gasoline. It is worth noting that, despite the similarity with other tools, it does not have a gearbox. And it is replaced by a kind of single-stage chain transmission, through which the chain itself (saw) is moved.
In fact, a chainsaw is a fairly simple design, but this does not prevent it from being reliable, practical and able to fully provide direct uninterrupted and cyclical operation even in fairly difficult conditions. This tool consists of a huge range of certain “vital” elements for its correct and productive work. This is a carburetor, a direct chain tensioner, a tire equipped with a chain and other elements.
Before buying a chainsaw, be sure to study all the options, and choose the brand of chainsaw that suits you.

Why does the chainsaw immediately stall and choke when you press the gas
Chainsaws are quite reliable and uncomplicated designs. Therefore, if you properly care for them and handle them based on the recommendations of the manufacturer, then they fail well, very rarely, various kinds of breakdowns are quickly eliminated. But if you are faced with this situation and want to repair your tool yourself without resorting to the help of professionals, then delve into the information below.
As a matter of fact, it is impossible to determine unambiguously and precisely the reason why the tool does not start or stalls when you press the gas, as there are a lot of factors influencing this. But do not forget that starting from the fact that the chainsaw is equipped with a simple two-stroke engine, conditions such as lubrication, fuel, spark and air are important for its effective performance.
Consequently, the carburetor is directly involved in the preparation of the fuel-air mixture, the filter purifies the air from dust, the ignition unit and the spark plug create a spark, and gasoline contains grease.
That is why it is necessary to search for the causes of this type of breakdown in a sequential order, starting directly from simple and gradually moving to complex. And this is an important factor in proper repair, as the person who, without thinking, begins to parse the carburetor, puts her at risk. Since this kind the unit must be repaired or adjusted directly in special workshops (read about carb adjustment).
Important is the fact that for trouble-free operation of the tool, it is necessary to be quite careful about fuel directly. Since if this kind of mixture is not prepared correctly, then most chainsaws simply will not start. Therefore, not every owner will guess the reason for the breakdown in the fuel. That is why in order for your tool to always work correctly, you need to use exclusively high-quality gasoline for the mixture.
And also use only the oil that is made by the manufacturer of your tool. In addition, it is important to prepare this kind of mixture in the amount that you accurately use in one or two weeks, but no more (see the proportion of gasoline and chainsaw oil).

Since in another case, overexposure of the mixture directly in the canister will lead to the fact that it will lose all its octane properties and this will lead to significant problems with the tool.
Blend when the mechanism is running
The cause of the breakdown can be immediate pouring a candle mixture at a time when the mechanism is running. In order to solve this problem, it is necessary to turn out and dry the candle, but remember that you can not calcine it in any case. Excess fuel must be drained through the hole (candle), wait 20-30 minutes, then install it in place and try to start the tool again.
There is no spark and the chainsaw is not gaining momentum
The chainsaw stalls when you press the gas due to the fact that no spark. This can happen when there is no good contact between the tip of the plug and the wire (high voltage). However, if this kind of connection works correctly, but there is still no spark, the whole cause is the ignition unit (electronic). It is important to note that this kind of spare parts cannot be repaired, so they can only be replaced.
Do not forget that by inspecting the candles you can get significant information regarding the breakdown of the chainsaw. Since if its surface is dry, the reason for this is the cylinder, which does not directly supply fuel. That is why you will have to step by step check the entire spectrum of its submission. If the candle is all in black soot, this means that the carburetor is not working properly, that is, it either supplies a lot of fuel or pours oil directly into gasoline.
Not enough fuel to feed and operate the chainsaw at full power
If the chainsaw stalls when gas is added, it means that the fuel is not supplied enough for the full operation of the chainsaw. This may be due to clogging of the carburetor (its nozzle), or contamination of the filter itself (fuel). Remember that the first node should be checked exclusively by professionals, but you can clean the second one yourself.
The filter is dirty
Since, for example, the Stihl chainsaw stalls when you press the gas for a simple reason, namely a simple clogging of the direct breather.
In order to solve this kind of problem, all you have to do is disconnect the hose (fuel) from the carburetor and pay attention to whether fuel is leaking from it. Since if the mixture flows in a full stream, this means that the breather is not dirty, but if it is the other way around, then the cause of the breakdown was found.
Muffler, as the reason that the saw stalls when loaded
Here’s another reason why the chainsaw stalls when you press the gas. muffler. It is this detail that can interfere with the full-fledged operation of the tool in those cases when it is directly contaminated with exhaust resinous deposits. To do this, you just need to clean it.
Cylinder piston group
Quite often, the Partner chainsaw stalls when pressed and the reason for this is cylinder piston group. Since by inspecting them, namely the piston and cylinder, it is easy to determine the cause of a tool malfunction directly by replacing them. You can also make a direct bore of the cylinder itself relative to the size of the new piston.
But if after inspection you find that there is no damage to either the piston or the cylinder, in this case the cause may lie directly in the rings (piston). For this kind of check, it is necessary to insert a piston into the cylinder and gently begin to swing it by means of a connecting rod. If suddenly you feel a backlash then the rings need to be replaced, as they have already worn out.
Insufficient chain lubrication prevents start and saw does not develop speed
Many people ask the question: why does the chainsaw stall when I press the gas? The answer may also lie in insufficient chain lubrication (see oil for the chainsaw chain), as the oil pipe may leak or the direct channels may be clogged. That is why pay attention to the chain, because if it is dry, without delay, start cleaning the channels that supply oil directly to the tool bar. After that, examine in detail the parts where the oil pump fittings are connected to the pipes. But if you notice that the oil is leaking at the joints, or if there are cracks on the pipes themselves, then in the first case, seal the leakage points with sealant, and the pipes will have to be replaced.
First of all, what you should remember when acquiring this kind of tool is that certain parts of the saw must be replaced with new ones after their useful life has expired (passport). It is for this reason that the instruction should always be at your fingertips, since everything is described in detail there.
These details include: asterisk (leading), bus, part of the system (anti-vibration), as well as a chain. Since we should not forget that if this “stuffing” is not replaced with a new one at the right time, then these worn-out spare parts will negatively affect the rest of the chainsaw. For this reason, often enough do a check of the depth of the direct tooth extraction. Remember that it should not be higher than a week of 0.5 mm.
Definitely, every thing we have purchased has its own expiration date and sooner or later it breaks and how insulting it is when the degree of breakdown is so great that it cannot be repaired. But you must admit that quite often we simply neglect the technique (see about proper operation and how to cut down a tree correctly so that it falls in the right direction), and when it stops working, then we try to find ways to fix the breakdowns, turning to a huge number of services.
But remember that even though the equipment breaks, we can extend its “life”. All that is needed is to simply look after her, run in after replacing parts (see how chains are run in here) and keep her spare parts clean and tidy. And then, undoubtedly, it will serve for many more years. It is also important to use exclusively high-quality spare parts and “additives” (see nozzles for chainsaws). Then your equipment will run smoothly, and you simply forget what repair is.
We also recommend that you familiarize yourself with the Stihl ms 180 chainsaw.
