i just bought a carb and some other parts (to get my new to me 041 farmboss stihl going again) from a fellow on Arborist site beofore Gary Banned me again LOL. i'm not winning or anything about his call its his job on that site to do.but any who the carb has been rebuilt and cleaned.but one problem i got is when i start it and try to retune it like he told me too.it don't do nothing but over load even when both screws all the way in. and it never does get full throttle.but it will set and idle for about 10 to 12 seconds i guess and then choke out.i knew how to post a video on here i would get a video of it.but it will spit mix out the top of the carb and out the muffler. i'm about to the end of my ropes with this thing. i'm about to take it to the stihl dealer tomarrow and see what he can do.But i wanted to come on here first and see if anyone knew what i can do to get it going like it should.
