    1936 Midget engine from Popular Mechanics magazine plans

    Jason, excellent build. I had been thinking of making a 1 inch bore version of the Midget for quite some time, because really the Midget isn't very small. Remarkable how your engine sounds exactly like mine! Thanks for sharing this.

    Kerzel hit&miss by Mike

    The angle for the valves and spark plug holes appears to be 120 degrees the “half moon” shape would have to be just large enough to seat the base of the spark plug gasket. It would vary somewhat according to which plug you choose. I think Dave made his own plug. Finally, 45 degrees is the...

    The engine in the article is actually called a 10cc racing engine. It was a model boat class at the time. When compared to the Elmer Wall Water Witch it is the same engine. The magazine plans in the article are accurate and the engine can be built using those drawings. You will probably need...

    My First Engine Build

    Yes the bypass is the passage that allows the fuel charge to “bypass“ the piston. If you are seeing fuel coming out of the front bearing it should be going up over the piston. It’s normal to get a little during running as this helps to lubricate the crank shaft.

    My First Engine Build

    That flat on the top of the back plate is for piston clearance. If you didn't need it, I would suspect that your piston might be too small, or the wrist pin might be in the wrong place. Either of which would affect porting and thus the ability of the engine to pull fuel. Make sure that the...

    Jim: I can recommend using sand from Budget Casting supply. I buy 50 pound boxes online. It is an oil sand works great with aluminum. I used it to cast my Atkinson engine flywheel. Other than that you could try adding a little extra water to your sand then after you pull the pattern out...
