Joe could you post your peice on staking the support ring for a mag plate. A search produced no results. I have a real sloppy one here. This one may be beyond saving. Thanks.
 
Yup, I can handle that.

(Magneto Armature Plate)
(J. Reeves)

If the armature plate has a a loose fitting, wobbling motion (the plate that the points, coils etc are attached to), it is usually caused by a slightly worn support ring. This allows the point setting to change erratically as the armature plate turns.

The cure is to remove the armature plate so that the support which is attached to the powerhead with 4 screws is visible. Then, with a screwdriver and hammer, or some tool of your choosing, and looking straight down at the support ring, make an indentation at what would be called the 12, 3, 6, and 9 O'clock positions. Install the armature plate and check for a smooth turning wobble free movement.
You may need to do that procedure a few times to obtain the proper fit (not too tight, not too loose), but it's worth the effort.

Use a small amount of anti corrosive grease between the aluminum ring and the brass support plate and also on the brass bushing of the armature plate when all is well.
 
Thanks Joe

Definitly did the trick, turns real smooth. It's a shame it turns out to be a gut job. She's been rode hard and put away wet one too many times. Winter project.
Thanks again.
