[SEL] Wico type EK magneto help wanted

[Rupert]

	Thanks Arnie for your reply and the info. My plan is to make a new 
bushing to fit the armature. The locating pin isn't worn appreciably as 
the diameter measures the same at the top and the bottom where the 
armature doesn't touch so it should be fine. I would like to know how 
tight to make the fit of the bushing to the pin.
	I will keep Mark's Magnetos in mind as it appears I may have more older 
magnetos to look at.

	Thanks for your help.
