Abstract

A choke system for an internal combustion engine includes a carburetor having an air intake, a choke valve disposed in the air intake, and a choke lever coupled to the choke valve, wherein the choke valve is movable between a closed position and an open position, a mechanical linkage coupled to the choke lever, and a solenoid attached to the carburetor and coupled to the mechanical linkage so activation of the solenoid moves the choke valve, wherein the solenoid is activated in response to activation of a starter system of an internal combustion engine, thereby moving the choke valve via the mechanical linkage to the closed position.
