Although one person can easily carry this engine, it still has as much power and torque as the old cast iron models. This homemade engine has 31/2 inch x 31/4 inch bore and stroke. We decided to test our fabricating skills on this one.

Setting out to build almost everything, we made the 15' flywheels, crankshaft, head, block, frame, and even the drip oiler. The pieces we didn't make though, were the sleeve and piston, which are out of a Farmall Super C; a Briggs and Stratton flywheel and coil; and also a set of Kohler points for the ignition.

Wanting to keep the friction at a minimum, we used the ball bearings on almost every place possible. Pillow blocks were used to support the crankshaft. Regular ball bearings on the cam shaft, cam follower, and even one in the rocker arm. Not much drag on this engine. It took too many hours to count to build and half as many more to polish it. All in all, though, I don't think it turned out half bad.
