I just tried to install the main engine seal, I tried for about an hour. I think it's just wonderful how the hole and the crank don't line up. Anyway the seal now looks like modern art. $28 bye bye. I'm going to get another one tomorrow. I have to have it running by tomorrow morning. I'm going to file a BIG chamfer on it, and use a deburr tool to put a BIG chamfer on the hole. And if it doesn't work I'll be going away for a while to Shady Acres so I can visit all my new friends.
