Abstract
Disclosed herein is an engine operable between a low speed and a range of speeds above the low speed, which engine comprises a combustion chamber, a throttle operatively connected with the engine for movement between a low speed position for operating the engine at the low speed and a range of positions spaced from the low speed position for operating the engine within the range of speeds above the low speed, a fuel pump adapted to communicate with a fuel source, a first fuel delivery system communicating with the fuel pump and with the combustion chamber for supplying fuel to the combustion chamber subject to control by the throttle, and a second fuel delivery system communicating with the fuel source and with the combustion chamber independently of the first fuel delivery system, which second fuel delivery system includes a squeeze bulb adapted to communicate with the fuel source, a valve operable between open and closed positions to control fuel flow to the combustion chamber in response to operation of the pump and in response to squeezing of the squeeze bulb, a spring biasing the valve to the closed position, and a control for operating the valve including a manually operable member connected to the valve for opening the valve, and a linkage connected to the valve and to the throttle for operating the valve in response to advancement of the throttle from the low speed position to locate the valve in the open position so as to introduce fuel from the fuel pump into the combustion chamber for a predetermined time interval.
