They have very minimal cracking. Could be sealed very easily. Point gap is .018 stamped on the mag plate. I will take the rest of the day and clean everything up. If I can figure out how I will post some pics.
Much appreciated

What should I use to seal small cracks in the coils?

Hey Dave, going to make sure these are no good first.
Thanks

Do a search on Corona Dope

Here’s a good tutorial on testing coils. I have tested 30-40 scintilla coils with this method. The cracking typically makes them bad but not always. And conversely, those without cracks don’t always test good.

So far 2021 is working in my favour. I have good spark at plugs. Turns out it was condenser and dirty point issues. when i tested the coils i had my meter on the wrong setting. Senior moment!
Waiting for parts for the lower end. On to the power head. Then blast and paint.
Anybody have an idea where i can get the period correct paint?
Also when i rotate the the crankshaft it is very stiff to move?

Thanks for the help Guys.
Happy New Year
