It's a Fairbanks Morse. It looks to be the old type R. Model 4B4 was made for an Minneapolis Moline tractor. I don't think parts are available for the old type R magnetos.

You tractor would have had the FM type F4B3. The later replacement mag was a type X4B3. The rotor,condenser,and coil are the same. The points are different for the two magnetos.
 
I made a mistake. Should be type J4B3 not type F4B3.

Can't see your new points very well. I think they are type J.
 
thanks guys, going to continue to try to fix this thing it may have to be replaced though if parts arnt arouind
