6 Main Bypass Valve Hard Anodized Aluminium suit Petrol / Gasoline & Methanol
Product Information
Main bypass valve, 6 AN male flare, hard-anodized aluminium, screw together, for gasoline and methanol. The main jet is the most basic adjustment of a constant flow metering system. A smaller main jet makes the engine richer, by allowing less fuel to flow back to the tank and forcing more fuel to go to the engine. A larger main jet makes the engine leaner, by allowing more fuel to flow back to the tank which means less fuel flows to the engine. This valve also acts as a check valve to hold pressure for starting and idling. We highly recommend plumbing this valve after the fuel filter, since any dirt or sticking may cause the engine to idle poorly or possibly not start.
