NOTE:
The Piston Spring phased out heavy weighted pistons, designed to produce a resistance to the rising suction piston in order to balance the venturi size with the correct mixture/air flow.
The ultimate aim being that the engine should be able to produce full power with the Piston fully raised together with progressive acceleration and steady cruising over the whole range of driving.
Rich mixture for fast acceleration being provided by the Damper.
THIS SPRING IS FOR NORMAL SUCTION CHAMBERS (IT WILL NOT SUIT HIF OR BALL BEARING TYPE CHAMBERS)
