Abstract

This invention provides a low cost, easily installed means of supplying supplemental fuel to an engine for the purpose of cold starting and enrichment, which also functions as a means for manual operator adjustment of low speed fuel flow. This system is easily adjusted by the operator while driving, requiring only one adjustment for a multi-cylinder engine. This system reduces the fuel delivery imbalance caused by the phase relationships of the fuel pressure pulses and the pressure pulses existing at the outlets of its fuel delivery orifices by using orifices of different areas.
