While we're on the subject, i have an old Husky 35 chainsaw that's been a real bear. It's only a small saw for misc projects when i don't want to trash the new one. The problem is it's really tough to get it started, need to be pulled at least a dozen times full choke, even when 90 out. I believe the plug is dry if removed so it seems it might be lack of fuel. Compression is good, new plug, clean air filter, fresh gas. Once it does start, i need to lightly feather the throttle to keep it running but too much and it'll die. Once running it runs great WOT but if yoy let up on the gas it'll die right out and wont restart till it cools all the way down. I've torn the carb apart and put new gaskets in plus tried setting it to factory specs but it still wont run right. Do you think the float setting, or what ever it's refered to in 2 stroke engines needs adjusting and how do you set it?
You mentioned it's really easy to set these too lean, how do you NOT set it too lean, hi idle adjustment or lo? What i usually do is try and set them to factory then minor adjustments to get it sounding good. I also heard that it's better to set the high idle first then low, but this is in regards to an old outboard motor so i don't know if it'd apply to all 2-strokes. Thanks for any advice.
