In this regard, why does my chainsaw keeps cutting out?
A clogged air filter is usually the most common reason as to why your chainsaw keeps on stalling. This is purely down to the fact that if an air filter is blocked in any way, it will have a knock-on effect to the air circulation within the machine and subsequently kill the engine.
Additionally, why does my chainsaw overheat? Chainsaw engines run at high temperatures, usually in the summer, so they can quickly overheat. If dust, wood chips or other material blocks these systems, the engine will start to overheat. The engine also needs to expel hot air, so the muffler must also be kept clean to keep the engine from overheating.
Keeping this in view, why won't my chainsaw start when it's hot?
Re: Chainsaw won't re-start when Hot Typically when a chainsaw wont start when warmed but starts and runs fine when cool, it's because the air/fuel ratio is too rich (too much fuel). It starts fine when cold because extra fuel is the same as using a choke. When it's warm and still too much fuel, it's flooding.
Why does my Stihl saw keep stopping?
An engine stalls when it's getting too much or not enough fuel from the carburetor. Stihl chainsaw carburetors usually have three adjustment screws: one each for idle, low speed and high speed. If the saw is stalling when you pull the throttle trigger or it doesn't reach its full power, adjust the high-speed (H) screw.
