I got this engine in November 2005 from the gentleman who made it. He bought the casting kit from DeBolt in March 1987. I have the original bill of sale with the prints on how to machine the castings. In the notebook with the prints are notes on what he did and also a note saying he spent 143 hours doing the machine work.
I saw the engine after it was made but not running. In the 18 years he had the engine, he never tried to run it.
After I got the engine, I put a coil in the base, wired the igniter and tried to get it to run, but could only get a pop once in awhile. After I had a new check valve made, and worked with the igniter, it ran.
With more adjustments and diddling, it runs very good now at 350 RPM. It will fire, then coast 12-14 revolutions and fire again.
I don't know why the previous owner never ran the engine. The regret I have now is that the self-taught machinist has died. I would have liked to have been able to run it for him.
