The THIRTY had a number of different pistons depending on altitude and fuel. Did the low compression (kerosene) piston have 4 or 5 rings? What was the compression ratio on gasoline and kerosene? If the Ensign carb was used for gasoline and alcohol will this engine be happy with the crap gasohol of today?
