Magneto filled with engine oil

Wed Aug 18, 2004 7:41 pm

I've had a starting problem with my 1948 Cub. My tractor has a magneto with no coil. For the past year it has been hard to start, needs choke to fire and then I must try six or seven times before I can get it running. Took Zenith carb apart, cleaned it -not much improvement. I replaced the plugs and when I took the mag off to replace points/condenser I found the magneto was filled with engine oil. The points were submerged in oil. I am surprised it fired at all. There must be a bad seal somewhere. Any advice on how to replace the seal, and where to find it, would be greatly appreciated. Thanks,

The seal that's leaking is the governor seal just in front of the mag. Go to Rudi's site:
There's lots and lots of great infromation there.
