This is my first Internal Combustion engine project. It is an air cooled hit & miss engine of my design. It has a 1" bore and 1.25" stroke. The valves are stainless steel. I have made all the parts including cutting the timing gears. The piston has two rings. It has excellent compression. The cylinder, piston, and rings are cast iron. It is complete except for the ignition system. The the real test, will it run???? More later.
