Giday all, ihave a fs55 stihl that I just can't seem to get right [Linked Image]
When I got this machine it was hard to start and when you throttle up it just died. I have cleaned the carby ,let it soak in dishwashing detergent overnight put the needle wire in every little hole a good blow out and now it starts after about three or four pulls ,it hits high revs no worries if you pull the trigger quick and drops to a fairly good idle. If I slowly pull on the trigger it picks up revs and about a third of the way up it starts to bury and if I hold the trigger there it will die but if I give the trigger a quick pull it will get past this point no worries . So it seems to be all good except it has a flatspot .What ould the cause of this be?ps this post wouldn't let me choose ussb for photo,sorry don't know how to fix this either. Cheers
