She's got a nice set there Fred!
Ahhhh .... Stihl products are now on my list. Getting parts online is similar to getting parts from GM or Harley-Davidson. Everything is a big secret! No online microfiche, & hardly any parts available besides on eBay.
I think I may have mentioned this last coffee about a Stihl leaf blower I was working on ....
Either way, had to head to the local dealer (which is what they want I suppose), drop $50 (
) on a coil, then get caught in a monsoon on the RD. 10' up the road, everything was dry ... and I was almost dry by the time I got home. What a day!
Anyway this thing is a HS80 hedge trimmer. Would run great wide open, but die the minute you tried to idle or run at part-throttle. After dismantling the entire unit I found a pinched/cut spark plug wire, with bare ignition kill wires which were arcing on the block. The connectors were oddballs, so I cut & soldered them to some thicker jacketed wire (stock was so thin it's a wonder it lasted as long as it did), shrink tubed the cuts, then wrapped the whole length of the pair with electrical tape. Should last a bit longer now before cutting through. With no help available on the net, it took much longer than it should have to figure out how the handle came apart (multi-position handle that rotates), then how all the springs went back together for the throttle & stupid safety lockout. She's all back together now & starts first pull.
