Anything I can help you with?

[@frontlinemedia4270]

I doubt this as the problem. I think the problem is the space between the flywheel and the pick up. Air gap needs to be checked

[@Letsdoittv67]

Either way end of the day, you’ll need to replace the flywheel. After some digging it was fairly common for these years to have a flywheel fail prematurely

@@Letsdoittv67 you have to check ohms and voltage. If there's a physical defect, that's a different story. If magnets come loose, like a on steel flywheel, you can re attach them. A lot of ppl take guesses and never really solve the root problem.
