Abstract
A carburetor improvement comprising a step-up spring (S) seat (1) attachable to a metering rod lifter (L). The step-up spring bears against the spring seat rather than against a step-up piston (P). Part throttle adjustment of the step-up piston position on the metering rod lifter does not alter the step-up spring force from that which the step-up spring is designed to exert when changes in engine vacuum occur and a throttle shaft (TS) is stationary.
