ABSTRACT:
A diaphragm carburetor with both the main metering nozzle and an idle circuit supplied with liquid fuel from the same metering chamber and an accelerator and shut-off assembly in the idle circuit. The assembly has a valve which is open to supply fuel to the idle circuit when the throttle is in a closed idle position and closes off the supply of fuel from the metering chamber as the throttle is moved to its wide open position. Opening of the throttle also actuates a piston to supply additional fuel for accelerating an engine.
