If its a vacuum secondary carb like a Holley, you may need a lighter spring in the vacuum pod. It controls the rate at which the secondary throttle blades open up.
If it stumbles when you floor it, then it needs more accelerator pump shot to cover the extra rush of air it gets when the throttles are suddenly smacked open.wouldnt a heavier spring keep it closed longer? im tryin to decide if its the accelerator pump adjusted to much or to less, or if its them vac's
in nuetral it revs great, just on the road it hesitates
not to mention now i noticed a bad stumble around 4800, thats in nuetral no load, i know things are different without load but.....
might have something to do with when i have 100% throttle in a mud hole and if it bogs down to stall ill push the clutch in and it wants to stall. im thinkin to much fuel on top makes it stumble/gurgle and load up with extra fuel
sorry guess i had more questions then i thought, and i dont no much about the carb, i had it there so i used it, just a holley with vac's and one accel pump and 2 fuel screws
