I put it back together. I hope I got the ring in correctly. It is impossible to slip the connecting rod onto the crank shaft with the liner totally inserted in the sleeve. I had to slip the piston into the bottom of the liner just enough to compress the ring. Then I dropped the liner and partially inserted piston into the sleeveso I could slip the rod over the crank arm.

I will start it up tomorrow and see if it self destructs or not. []
