I'm looking for a John Deere Model 50 WICO Model XB Magneto Cap. It seems that the XB is rare. Does anyone know where I can get one. The cap is for a single leg rotor and the posts inside the cap are on opposite sides of the cap while the outside connections are on the same side as shown in the photos.

HMMMM, mite have to get a 2-legged rotor to go with that cap.

Call Brillman, they are very knowledgeable and can tell you for sure what will work.

Thanks for the information. I happened to find someone who has one like the one I posted. I would prefer to use the same configuration as original rather than trying the X series with a 2 leg rotor. I will be back on this forum if that doesn't pan out or if I need something else. Thanks again.
 
Those Wico XB's were no good when new. Many have been changed to a Wico XH or a Delco distributer
 

I have the exact same set up on my 50, it is not a magneto although at first glance you would think it is. The cap is hard to find, a cap off a jd A will not work, trust me, either will a 2 prong rotor. Try magnetoparts.com 978-649-7879, local guy up in Massachusetts, he has hooked me up numerous times, good luck
 
I fought one of these on a late model B. Finally I said screw it and put on a magneto that I had lying around. Tractor runs fine with that. But if you want to stick with a distributor, then upgrade as others have said.
 
Thanks for all the good information. I have an XB cap on order and will let y'all know how (if) the tractor runs after I install it.
