ABSTRACT:
An engine comprises a combustion chamber and a throttle movable between a low speed position for operating the engine at a low speed and a range of positions spaced from the low speed position for operating the engine within a range of speeds above the low speed. An enrichment fuel delivery system communicates with the combustion chamber and a source of fuel and is operative for introducing fuel from the fuel source into the combustion chamber. The enrichment fuel delivery system includes a control mechanism which is operatively connected with the throttle. The control mechanism operates the enrichment fuel delivery system in response to advancement of the throttle from its low speed position to introduce fuel into the combustion chamber for a predetermined time interval.
