Abstract
The two cycle engine has a combustion chamber supplied with primary fuel for normal operation. An electrically operated priming system delivers fuel in addition to the primary fuel. A control regulates energization of the priming system. A momentary switch energizes the priming system when the switch closes and enables the control when the switch opens. The control causes the priming system to operate a predetermined period of time after the control is enabled but is subject to override by a switch responsive to engine temperature. Thus the priming system is shut down by the temperature responsive switch when engine temperature exceeds a predetermined value. The timing function of the control is provided by an integrated circuit chip wired as a timer. When the engine is started the timer chip is reset to zero and the timer starts timing when the momentary switch opens.
