Cuyuna 430
The Cuyuna 430 and Cuyuna 340 are a family of two-stroke, twin-cylinder piston snowmobile engines that were redesigned to serve as ultralight aircraft powerplants.Cuyuna Development Company: ''Cuyuna Engines'', Cuyuna Development Company, undated Development While developing the Pterodactyl Pfledge flying wing ultralight in the late 1970s, designer Jack McCornack experimented with a number of possible engines. Early flights used a German-made Sachs engine, but the high exchange rate and long lead times for this engine convinced him to try other options. McCornack settled on a snowmobile engine produced by the Cuyuna Development Company as having the best potential. In 1979 he modified the engine with a crankcase extension, an additional main bearing, lowered the compression ratio using an additional head gasket and substituted a smaller Mikuni carburetor, amongst other modifications. The original snowmobile engine produced . Lowering the compression ratio not only de-rated t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
