ABSTRACT:
A carburetor has a choke apparatus including a pulldown servo to crack open the choke valve a predetermined amount once the engine has attained a running condition, to lean the air/fuel mixture. The conventional bimetallic spring is included to slowly open the choke valve wider. A locking lever is provided to lock the choke valve against return to a more closed position than that attained by the pulldown servo, to prevent stalls due to cold engine loading and loss of vacuum; the lever, however, freely permitting opening of the choke valve and also including means to reset the locking lever so that the engine can be restarted with a closed choke valve.
