1992 but it would not run. It had very poor compression.

I had to hone the cylinder, weld the piston and make oversize rings. Then I belted it up to an electric motor and ran it for many hours to wear in the rings. It now has good compression and starts and runs nice.

It has 1 inch bore and 1 inch stroke. The eight inch flywheel is heavy. It came off another compressor. The gears are from a small Continental engine. The gas tank is from a brass pipe. The carburetor is a small brass valve and a lawn mower needle valve. The governor is made from scrap brass and steel. The muffler is the original air cleaner with larger holes and the nickel plate removed. The 10 mm spark plug is in the air outlet hole. I made the valves from scrap steel and the head from a brass pipe plug. The base is from scrap steel.

I have run this engine all summer at the 1994 shows and have had a lot of pleasure from it.
