ABSTRACT:
A solenoid operated cut valve controls flow through a vent passage leading from a float chamber for a carburetor for an internal combustion engine. A normally closed switch opens in response to high temperature of the engine, and a normally closed timer switch opens at the start of cranking and closes again after a predetermined time of cranking. The switches are connected to the solenoid to prevent increase in pressure within the float chamber from delivering an excessive amount of fuel to the air intake passage of the engine. In a modification, a switch responsive to vacuum intensity in the intake passage is included in the solenoid circuit to facilitate acceleration of the engine after a hot start.
