Well some people have a sense of humor and evidently some don't but saying that it's nearly impossible to trouble shoot anything over the internet .A 10-10 righty is about 50 years old and Lord only knows how many people tinkered with it in that time .--and if if it were my saw, which it's not I don't get frantic about anything especialy on a chainsaw .If they frustrate me ,which they have they just go on the shelf for a spell until I think out and so far I always have given enough time .One time on an 042 Stihl that saw was punished for about 2 years before I got back on it .
One cannot expect to show up on a forum ,pop a few questions and expect some miracle fix fall out of the blue from somebody 500 miles away who has never seen the darned thing and never will .So saying that best of luck .
