I have a 288xp supposedly rebuilt recently. was running fine a while ago, then developed a problem of not staying in tune. I thought the screws were backing out as I had to reset them and it would load up and run pig rich after working with it a little bit. so I replaced the needles and springs. would last about 15 minutes before it would run rich again. so I ordered a brand new tillotson carb for it. needless to say that wasn't the problem obviously.
Saw will run with high screw shut all the way and not run lean. will also decrease in idle and almost die if I roll it sprocket side up, will not tune right with low screw either. Cant seem to figure this one out as I thought air leaks made them run lean.
I recently had the oil pump out of it, the seal was reseated on that side (sprocket) and everything looked fine and went back together the way it should, I was watching the tech do it and he's pretty reputable around here.
Thoughts????
