Why does my chainsaw stall when cutting?

The carburetor might be clogged. A clogged carburetor is often caused by leaving fuel in the chainsaw for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the chainsaw engine to stall.

Why does my Stihl chainsaw dies when I give it gas?

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 stalls while it’s idling, adjusting the idle screw, which usually is marked LA, should help.

How do you adjust a high speed screw on a Stihl chainsaw?

My opinion the only proper way to get more torque out of a chainsaw, is to lower the “gear ratio” at the drive sprocket. That is run a smaller drive sprocket. Back in the day gear transmissions were a very reliable way of producing extra torque. ….. Making a living with a saw since age 16.

Why does my chainsaw bog down when I give it gas?

If your chainsaw is bogging down when you give it throttle, this is often a sign of improper gas-to-oil ratio. If there is too much gasoline in relation to the amount of oil used, this is known as a “rich mixture” and can cause the chainsaw to run poorly.
