I posted this in 'Tool Talk" also...While I was clearing fence rows with my tractor....
Last fall I was out clearing some fence rows and came across a Stihl 038 AV chainsaw that I had forgotten and left there for 12 to 13 years ago.
Anyway, I was bored today and wanted to see if I could get this thing to run. When I found it I had soaked the cylinder with ATF to free the piston and rings. Chain and bar were rusted together so I just discarded them.
I have great compression but no spark. Cleaned the flywheel and EI module contact points plus all the grounding contact areas.
All I can think is left is the EI module is bad, (can they go bad?) or a faulty ignition switch.
I'm going to bypass the ignition switch next.
BTW, Plug is good.
Thanks, Greg1959
