ABSTRACT:
A decompression device for an engine reduces pressure in the engine's combustion chamber thereby reducing the amount of force required to start the engine. The decompression device incorporates a decompression lever that cooperates with a cam surface to hold engine valves open longer than normal while the engine is being started. The decompression lever has a weight section and a lifter section. The lifter section is located near a pivot location on the decompression lever and is generally the same thickness as the weight section. The lifter section protrudes beyond the cam gear to hold the engine valves open longer while starting the engine. After the engine has started, the decompression lever rotates into a retracted position to allow the engine valves to open and close normally.
