Can you clean a chainsaw carburetor without taking it apart?
Run it and it should clean it as well as you can get it without taking it apart. I used it a while back on two saws that had set for two years and it worked on both. The small saw started after about ten pulls and would idle but rough so I shut it off and let it sit overnight.
Why does my Stihl chainsaw keep dying?
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.

The most common problems why a chainsaw does not stay running are: Spark Switch/Plugs. Bad Fuel. Blocked Carburetor.
Is it worth rebuilding a chainsaw?
Tree Freak. As long as you didn’t damage the plating in the cylinder, it should be worth rebuilding. I never fire up used saws until I made sure the fuel system is in good shape, the bearings and seals are tight, and there’s loose parts rattling around inside.
How hard is it to rebuild a carburetor?
