heres what it said about my dualstart dualclutch engine:
Dual GGG model; Allows pedal starting as well as rope pull engine start. Uses a friction clutch as well as a special centrifugal clutch with over running clutch lock up to pedal start; Handle Bar Clutch lever must be in the engaged position to operate in centrifugal clutch drive mode. In disengaged lever position the engine is in free wheel mode separated from drive line. Note: A standard friction clutch engine can not be converted to GGG dual mode due to different crankshaft
