[Farmall] Turning on the magneto switch on Farmall "H"

[Ron Cook]

I had a link at one time for a replacement pulley that works.  It seems 
like it was for a Model A Ford.  I cannot find the place.  Too many 
files and too many computer changes, I guess.  Bottom line is, there are 
pulleys being made that will work.
