Stocking parts for the famous Universal Atomic Four gas engine.

Boating Tip: The Canadian version  of the Atomic Four was rated lower than the American version due to a reducer bushing placed in the intake manifold just above the carb. Drilling out this bushing will increase the horsepower to 25 which was the US version rating.
