1980 G1 Golf Cart Engine

[bradgibson]

Hey guys, just took the new to us golf cart to the desert. Ran great at home, and for the first day at the desert, but then would not start and was spitting oil out of the front end of the motor at the case seal. After a few whacks on the starter with the hammer, it would engage, but not start. So I figured I need a new starter after reading many posts on this site. Now the motor is out and disassembled, head off, cylinder off, piston and rings off, how do I get to the crank to replace the seals?? Everything looked OK on the tear down, except for the reeds were shot and the top of the piston had tons of carbon build up. Carb was OK, Plug looked OK. All thoughts are appreciated.
Thanks
