why does my engine bogg down when i jump on it? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Today when i took her out, and eventhough i replaced my ACCEL with a higher output one, i still am getting a bogging down sound and acceleration when i jump on it, is there something simple i can check or what?

On the holley carb in our camaro we had to go to a larger accelerator pump nozzle to correct for a bog when slamming the throttle. We went from a .031 to a .035 if I remember correctly.

accelerator pump... umm forgive me but can you show me a picture of that, i think i know but not sure

If you go to www.holley.com and look on page 29 of their avenger carb catalog it has an excellent description and pic.

I am going to be in the Waukegan/gurnee area for Xmas. I can help then ith any powertrain issues you have.

Boise69 · 11-05-2006, 04:41 PM

thats a great offer but gurnee is 100 miles from me

my MIL will be there (Waukegan). it would be a good reason for me to dive out for a while.

Boise69 · 11-06-2006, 01:29 PM

man i would love the help or advice. when you say drivetrain what would be your specialty. i will be swapping my drums for rotors at that time and i'm sure i'll be scratchin a bald spot on the side of my head by mid december.

If changing the accelrator pump doesn't pan out you can also check the voltage regulator. My truck would bogg on acceleration untill I changed mine. Turns out that it wasn't keeping the 12v signal at 12v. (HEIs hate that.)

interesting! that would be an easier and cheaper fix for sure and then i should check the condition of that second wire running down to the starter?
