The rotary valve is likely gonna work to my advantage I think . It seems no matter how perfect I make the stock carb if the float gets stuck the carb will over flow . I don’t like that design . If I take the motor off and store it sideways in the trunk of a car or something I got a dangerous mess on my hands . The shut off isn’t going to work unless the engine is upright. The little carbs I have in mind don’t have any opening so upsidown rightside up they are not going to leak . Maby I don’t need to use the fuel pump feature as the tank is higher then the carb . I’m not clear on that . It may also be that no fuel will flow into the carb unless the diagram pump is actuated . I think the rotary valve on the crank shaft is probably why this zephyr carb works at all on the power stroke the valve is closed and no pressure makes it to the carb only vacuume makes it into the carb . So I have two schools of thought . Will a series of vacuume pulses actuate the fuel pump in the new style carburetor without any pressure to flex the diagram in the opposite direction. Or can I just have it gravity feed. Can the carb fuel lines be connected in sereas, as in fuel outlet to fuel inlet of the next carb as long as the last carb returns a little fuel to the tank then I know none of the carbs are starving for fuel ? I’m gonna give it a try post some pics if it get it working .
