DT250B cracked magnet was created by Schu

I picked up another DT250B flywheel and stator to keep on the shelf for when my CDI craps outs on my DT360A. I’ve done that ignition swap on my other DT360A and my DT400B and I really like the results of going back to the old school points and condenser.

I bought this set knowing one of the magnets was cracked on the flywheel and I’m hoping I can still use it someday. Do you think it’s feasible to epoxy the cracked ends and maybe be dribble some thin superglue over the other hairline cracks that you can see in this photo?

Replied by Schu on topic DT250B cracked magnet

Never mind…….
I just realized that the cracked portions are actually a plastic insulator around the magnet and not the magnet itself. I don’t have the actual parts in hand yet, so I will confirm once I do.
