Hi, My name's Bert from Black Earth, WI. I'm here after searching for information on Jonsereds Chainsaws. I bought a Jonsereds at an auction for $20 3 years ago and happily it has started and run well ever since. until last week. Man, what a saw. Torque; all you want and power to spare. It was just what I heeded for my bigger red oaks.
I'll attach some pictures. No model indicated anywhere but the s/n is 2301627. I imagine the saw is over 30 years old.
No spark at all, and it has two coils. One at the flywheel and one at the spark plug. Neither show open Ohms but there just isn't a whisper of a spark. Eliminated the stop switch and there are no apparent shorts to ground or broken wires. So it must be one of the coils or both of them. Where do I go from here? Does anyone have any replacement parts or are there any modern schemes to go from the flywheel coil direct to the spark plug? I see there are several coils that do just that,
View attachment 196554View attachment 196555 but don't look like they would bolt on as a replacement.
I'd hate to give up on this saw, so I any of you have some suggestions I'd sure be receptive.
Regards
