I have a fairly new MS290 that ran great for about two years. When it quit running I replaced the plug, fuel line , fuel filter and put a carb kit in. I tuned H by starting one turn out. Then I started it and slowly moved toward lean until I got max rpm at full throttle. Then I opened H 1/2 turn. When I put it in wood, it did not have much power and smoked a bit. I turned H about 1/8 toward lean and tried again. It cut great and quickly finished off a chord of wood. Then without warning, it stared to burble badly at full throttle and had no power at all.
The air cleaner looks pretty dirty so I will clean it and try again. I was frustrated that I could not clean the filter in the woods. I really miss the foam filters that were so easy to clean while on the job. Does someone make a foam replacement for this saw.
I am also curious about what else may have caused this saw to go from running great to running so poorly in just a matter of minutes. Any ideas?
