    Mentzel, the accelerator pumps were disconnected years ago. Definitely not the issue. But I wish it was that easy

    Yep, some anti-siphon valves are too thick. Once in a while it will cause this issue. Just make sure you have the thin oem style. I usually just push a small screwdriver through the hole and see how much it bends.
    I've NEVER been able to tell which side is which on the FP check discs......and NEVER had an issue there through hundreds and hundreds of carbs.
