The basic engine was originally designed and produced by JLO of Germany and was later acquired by the AMW Cuyuna Engine Company of Beaufort, South Carolina and marketed under the Cuyuna brand name. Later the engine was marketed by Cuyuna under the Two Stroke International (2si) brand. Cuyuna no longer markets engines for aircraft use although the 230 was still in production as a diesel/multifuel or gasoline industrial and marine engine.
The 230 is a conventional single-cylinder two-stroke engine that weighs only 36 lb (16 kg) in its A20 version. The engine features single capacitor discharge ignition, piston porting, tuned exhaust system, slide venturi-type carburettor, fuel pump, a cast iron cylinder liner, ball, needle and roller bearings throughout. The engine was offered with cog belt drive or a gearbox reduction system. Starting is electric starter or recoil starter.
