Why does my Chainsaw keep turning while idle?
That’s usually a sign that the clutch needs to be replaced. The most probable — and easiest to fix — cause of chain rotation while the chainsaw engine idles is a poorly adjusted idle setting on the carburetor. The result is that too much fuel is delivered to the combustion chamber when the throttle is released, and the engine doesn’t really slow.
What to do when your chainsaw Won’t Stop Spinning?
When turning the screw clockwise or counterclockwise, watch for when the engine’s behavior changes both while you’re throttling it but also when idling. If the chainsaw won’t stop spinning when idling, or it’s smoking when it idles, it’s getting too much fuel and running rich, so you’ll need to back it down a bit.
What happens when the throttle is set too low on a chainsaw?
If this adjustment is set too low, the engine will die when the throttle trigger is released. The throttle valve (butterfly) simply cuts off the supply of combustible air/fuel and the engine stops. If this adjustment is set too high, the high idle speed will cause the centrifugal clutch to engage and the chain will run.
Why does my Chainsaw run when I change the spark arrestor?
Carbon clogging the exhaust port or spark arrestor screen can cause a saw to run as if the carburetor requires adjustment. Changing the carburetor settings with a plugged muffler may result in the saw running to lean when the carbon build up is cleaned out.
Why do chainsaw chains keep coming off and how to fix it?
Why Chainsaw Chains Keeps Coming Off and How to Fix It: Chainsaw chains come off the bar due to worn-out bars, worn-out sprockets, and wrongly set tension. You should also note that with continued use, chains lose their tension and hence are more likely to come off the bar when you least expect it.
Why does my Chainsaw stall when I press the throttle?
If your chainsaw stalls instead of producing the reassuringly high-pitched sound of a healthy engine when you press the throttle trigger, something is interfering with efficient fuel combustion.
What should I do if my Chainsaw dies while idling?
On many chainsaw models, you can control the amount of fuel that the carburetor sprays into the combustion chamber by turning one of its adjustment screws. If the engine dies while idling, the idle adjustment needs to be tightened.
Why does my Poulan chainsaw keep stalling?
A clogged fuel filter is often caused by leaving old fuel in the chainsaw. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the fuel filter and cause the engine to stall.
