Abstract
Several embodiments of charge forming systems for crankcase internal combustion engines each of which embodies a first charge forming device having a main fuel discharge that delivers a fuel/air mixture to the crankcase and a second charge forming device having an idle fuel discharge for delivering a fuel/air mixture to the transfer passage. The second charge forming device is provided with means for providing cold running enrichment. In addition, a priming fuel pump is adapted to supply priming fuel of a higher quality to the first charge forming device upstream of its venturi section. The two charge forming devices are each supplied with air from a common air inlet device that includes at least a air silencer. The communication of the second charge forming device with the air supply device is such so as to preclude the likelihood of fuel leakage if the engine is oriented in other than its normal condition.
