    Rumblefish, yes i looked it up...EGR Venturi port. So its not that causing it. I would say it is mostly likely the fact that i have no accel pump shot. So of course this will give the indication of no fuel in the bowls, when in fact there may be. Th ecarb is freshly rebuilt so i would like...

    ThermoQ -2 questions:

    I will tell you in a day or so. I have pulled the rubber vacport plug off that needle-like port sticking out at 45degress from the plastic central body. I will leave it a day of so and see if the problem persists. I also found out today that another contributing factor could be that the accel...

    Moronic fuel pump question...

    ThermoQ -2 questions:

    Is it Ok to ask two unrelated questions in the same post? Well here goes...! Q1: Can anybody tell me what might be wrong with my almost new TQ? Lately, after just 24 hours -ALL the fuel drains away from the float bowl, including in the fuel line to the carb. So that it will not start unless...
