At least it is for me. First time its happened. Got an 034 off this site that was mostly complete and decided to fix her up. Had some problems along the way, stihl evedently changed some parts slightly while retaining the same part no. Got her together, started her up but she'd quit after start up. Put a new fuel line in her, the vent was good, impulse line looked good, so I figured seals or base gasket. Shes old so seals wont hurt. Put new seals in and she did the same thing. This time she was torn down to the bare neccesities and I noticed she was sparking along the spark plug lead where it goes through the case under the recoil. It was causing it to short out. Took the coil out and looked at the spark plug lead and it looked fine, no visible cracks anywhere. Put another coil in and she ran fine. What would cause a spark plug lead to ground out if there are no visible cracks?
