Homelite Chainsaw Stalls

Have a 5-year old Homelite Chainsaw 16" 33cc.

Starts great. Idles Great. Cuts like a hot knife through butter.

Once it warms up, it will stall from idle no matter how carefully you pull the trigger.

Found out thiis weekend that if I am idling and flip the choke halfway out, I can accelerate to full speed and then push in the choke and cut like crazy.

Working at 8600' so I figured it was running rich, but the choke fix would indicate that it might be too lean.

Ideas??

Thanks FJ

Sounds like your mixture settings are too lean. Mark them (so you can return to current position) and richen them up. If you go too rich with the high speed, the engine won't reach full speed.

Thanks,

I should have mentioned that it has been like this since it was new.

If it is too lean will it damage the engine??

Too lean will cause it to run hotter shortening the life of the engine. I have a yard vacuum, 2 cycle, that came from the factory lean. It would want to quit unless I opened the throttle very slowly. I eventually scored the piston and cylinder wall. I replaced both and richened it up. It now takes a quick full throttle from idle whereas before it wouldn't. Too rich is preferable than too lean.

To Me it sounds Lean, You may have to adjust the mixture screws,, I have to ask, since you say the saw is 5 years old & had this problem since new, Why ask now & not have it fixed when it was new??? You may be into a carb kit & a cleaning now.... Sorry,,, Roger

On a two stroke especially too lean is suicide. The problem is likely the altitude and the mixture.

You've been running it with the choke partially on, then since it was new? You just haven't used it much?

Turn both mixture screws out about 1/16 of a turn, then set the low speed screw for good acceleration.

Once you have that, go back to the high speed and set it for max rpms, then turn it out another 1/16 of a turn to load up the mixture a little.
