Mark 25 Magneto

[tarcigam]

I replaced the coils in one about ten years ago. I have no recollection of what I used or where I got them. I do recall I had to pull them off the heals and remount them. Anyone know what I might have used? New ones seem to be rare and expensive if you do find them.

They don’t seem extremely expensive.

Or convert it to omc coils.

No one checks the caps or insulation values, great mags! Check each comonent, assemble & meter, Wax = bad dielectrics 60 years later 😳

You can substitute the OMC coils with a little work.

Tubs,
bought a MK 25 15 years ago & was running early honda motorcycles. Guy didn’t even change the caps or match coils, Fit under too but needed a battery
