    5-6 psi is a good mid road setting

    90% of the game is half mental... The pursuit of the unknown is priceless & gratifying . Sometimes it just takes good old fashion balls. No amount of reasoning or evaluation can deem it right or wrong. At the end of the day stick with whatever gives the person in question morning wood LOL

    all that check valve does is help it start after it starts the pressure will open the poppet valve and it will be open all the time.

    Am I wrong in thinking that the pressure in that will change how the motor idles because as the pressure goes up it sends more fuel to the motor before it kicks open. Or because its open as soon as the motor fires any way it won't matter?
