    Weber cold start flooding

    When it's really cold outside the it has no high idle, cough, choke, puke, and floods itself to death, I have a block a wood I wedge against the gas pedal till it warms up while I'm waiting around. Help setting and adjusting i guess is what I'm asking for. Thanks

    Before cold starting, press the gas pedal only once, or maybe twice if it's bitterly cold (near or below freezing temp).

    A properly-tuned Weber should not diesel after shutoff, even without any idle cutoff solenoid installed. Are your spark plug tips sooty-black? Sounds like your idle mixture screw and/or jetting may be set too rich -- or possibly fuel pressure is too high, forcing fuel past the float's needle valve and into the intake. Idle jets should typically be about a size 50 (+/- 5), and this thread covers basic Weber tuning:
