Removed power pack & coils to clean ground & reassemble.
Power Pack looks really bad. Coils look to be really old.
Is there any way to test this power pack or jury rig it just to get spark? Think it might be partially alive. I could feel a tickle when holding the harness & spinning the flywheel

Still finding my way around this site. Tons of useful stuff !! I would delete this post, but haven't learned how to yet, as it's in the wrong forum. Also, I've managed to find elsewhere on site that the Blk/Yellow wire is for the kill switch. Open to operate and ground to stop engine. Surprisingly, the nasty looking power pack is functional, now have spark on both cylinders.

Look through those, I don't think they have the exact one you need but you can use them for reference even if the colors might not match. Some of the larger engine will be wired the same for the most part, just with extra wires
