Thread: Secondary Bog

  1. #1

    Default Secondary Bog

    I have a 670 Avenger on my '79 Camaro with a 330 HP 350 crate engine. I’m still getting a lean bog even with the black spring. I’ve also tried the Quick Fuel secondary pod and put a silver spring in it, and had to turn the screw almost all the way in to get rid of the bog. Any suggestions?

    When do you get your bog? Is it by punching it wide open throttle? If that's the case, it might not be your secondary spring, as you should be able to use a lighter spring and not get a bog. What's your timing setup at as that can also play a part in things that can cause a bog. I've ran that carb many times in a Chevy S10 V8 swap, and I've always been good with a yellow or purple spring and never a bog, as long as my timing was right and having the right amount of pump shot.
