Abstract

A fuel system that in at least some implementations includes a carburetor having a fluid passage, a solenoid, a valve, a driver circuit and a control circuit. The valve may be moved by the solenoid between an open position permitting fluid flow through the fluid passage and a closed position at least partially inhibiting fluid flow through the fluid passage. The driver circuit and control circuit are communicated with the solenoid to contribute to providing power to the solenoid and controlling actuation of the solenoid. The driver circuit and control circuit provide a first magnitude of power to the solenoid to initially change the solenoid from its closed position to its open position and a second magnitude of power to maintain the solenoid in its open position wherein the second magnitude of power is less than the first magnitude.
