I have my 357XP that ran pretty good for a while when I first got it (used from a farm auction - great shape, no scoring). I started to have some reliability issues, and after checking everything out, found it to have a cracked fuel line. It also had the plastic boot clamp that was in the service bulletin and I ended up replacing that as well along with the fuel and impluse hoses. Since then, I have never gotten it to run right.
Pressure and vac tested everything, and all is good in that respect.
I can adjust the carb and get it to run really nice, but after about an hours worth of cutting, everything is back out of whack. Idle is way high and the saw seems to run lean at high speed. When I first got it, I replaced the tank vents because they were bad, so I don't suspect that to be the problem. I am starting to think it could be the carb. It is a Walbro HDA-175 which is no longer produced. I have no idea if there were suppose to be limiter caps on it or not. So, I really don't know if it could be working itself out of tune. Any other thoughts?
