Introduced in 1960, the OK Cub .024 cuin. glow-plug motor was the smallest I/C engine every offered by the long-established Herkimer Tool and Model Works Inc. of Herkimer, N.Y., USA. It was also the last such unit to be introduced before the company ended production in 1964.
The design of this little engine mixed the twin exhaust stack arrangement of the largest OK models, the 29/35 designs, with the updated design features of the OK Cub .049 and .060 variants introduced in 1958. These included Cox-style cylinder porting, radial mounting, reed valve induction and a head with integral glow element.
The Cub .024 has suffered in memory by comparison with its far better-known rival, the Cox Pee Wee .020 design. However, testing by Maris Dislers has revealed that in fact the much-maligned little Cub .024 could actually give its Cox rival a pretty good run for its money! All it needs is the right combination of prop and fuel.
