Jerry's Original "Howell V-Four" (V4)

"The engine is 1.95 Cu. In. (32cc) in displacement. Cylinders are 90 degrees apart in order to have the engine balanced for vibration free running. The cylinder bore is .875" and the piston stroke is .812". The cylinder banks are not staggered and robust knife and fork connecting rods are used. The multi segment built-up crankshaft and twin cam shafts are amazingly easy to make. A Hall Effect distributor is driven off the end of one of the cam shafts. The distributor body is linked to the throttle arm for spark advance/retard with the throttle setting. The throttle is my newest proven 2-jet design with an oiled foam air cleaner. " - Jerry Howell

Jerry running his Howell V-Four

Jerry Howell running his original "Howell V-Four" in his small shop in Colorado Springs, probably in 2006. Dad always liked to put his engines "to work" as seen by the light bulb attachment. Sounds great - hard to believe it's just 32cc!
