Working on Stihl MS250. Easy2Start. Not exactly broken, but takes one and a half pulls to trip the EasyStart spring. I have been told and see videos to "NOT YANK THE ROPE LIKE NORMAL SAWS". because once you do that, it will be screwed up from then on. So I have taken this recoil apart, (have NOT taken the secondary spring cartridge apart). I don't really see anything broken. But what exactly gets "screwed up" in the yank-pull ?? What should I be looking for, or truthfully, how do you go about fixing one of these supposedly screwed up starters? Perhaps it just needs cleaned up from sticky oil gunk in the spring, carb cleaner or whatever, folowed by WD40? that is my thought now. I don't want to take the spring apart to rewind if I don't have to, but would do so if necessary?
Would an Stihl 250 Shop repair manual go into this issue? I don't mind buying a manual, but at least want that part of the understanding to be in there.
I think I now understand the theory or the mechanism of the first recoil engages the housing of the secondary recoil mechanism and winds that part until it overcomes the resistance of the crankshaft/piston/engine etc? then once it begins spinning, it continues until the secondary spring is wound down to limp? Is that about correct?
Would like to hear explanations before I try to describe my understanding any further. Thank you for any comments.
