what carb do you have? Are you talking about the truck in your signature? Could be any number of things, I would start with checking fuel flow (filters, etc.). details would depend on the details! If it is a quadrajet and the filter(s) are clean, I would start by setting the wind-up spring tension on the secondaries to about 7/8th turn after it contacts the butterfly. If the secondaries open too soon, it'll cause it to bog.

i have that problem sometimes too. i kinda fixed it by puting it up to 12' timing but it still kinda does it. i got a edelbrock 1411 (big block economy version) could it be runin rich/lean?

Good carb. Loose allen screw about one turn and set the spring tension. If it's still doing then it's probablly a check ball for accelerator pump is not sitting right.

[oldblue1968chevy]

okay,i looked for the allen screw, couldnt find it, about to check the filters.

accelerator pump, what exactly is that.

point 406 im goin back outside to 70* weather to keep lookin!

Ok, block choke open. With the engine off look inside the carb and open the throttle. You should see a steady spray of fuel.
