MINIATURE HIT & MISS INTERNAL COMBUSTION ENGINE 

This is a video of my forth miniature internal combustion engines. All four engines are all scratch built from metal bar stock. A video of each engine running is posted on my RU-vid channel. This latest engine is a vertical cylinder, air cooled, hit and miss, four stroke, internal combustion engine. The engine has a 1/2 inch bore and 1/2 inch stroke and spark ignition.
