Alright guys this just doesn’t happen …. got a good one working.
I’ll give you the symptoms and you tell me what’s up??
It’s a Stihl MS660 starts fine revs right up to 13,000 but if you hold it at WOT for say 10 seconds it goes lean…. Will come down to idle lean, and if you hit the throttle on deceleration it will bog out lean, but if you let it idle for a few seconds it will recover and rev right back up to 13,000 and four stroke for another 10 seconds until it screams lean again.
Hit quitting time so I had to give up on it for the day, but the damn thing is haunting me. So lets see what the collective AS mind can come up with here.
Ask away and I’ll give you the results of the tests so far… maybe you guys can come up with something I’ve missed or trigger my little pea brain into gear on this one?????? :dunno: :bang:
Fire away!!!!…. I really hope I come out looking ignorant on this one.
