Operating Systems

How each system works: the float system with its check valve fuel filter and pull clip, the idle system and its sealed mixture needles, the main metering system with two stepped metering rods positioned by the solenoid plunger, pull-over enrichment, the accelerator pump, and the choke systems of the E2ME (electric choke) and E2MC (hot air choke), including the vacuum break units.
