Are you sure your idle ports ( size of pinhole) in carb aren't plugged with something? What happens if it starts to die, and you give it a quick squirt of WD-40 , down throat of carb?

SOURCE: 95 GMC Jimmy 4.3l W vin rough idle

My problem was solved when I repaired my 4 wd activation dash switch. The switch was contacting on 2WD & 4HI at the same time. The front differential activation is vacuum activated possibly creating a tug of war that didn't actually engage it but drained off vacuum from the engine? A theory at best but stumbbled across it because I knew the switch wasn't working properly I repaired it and low and behold rough idle disappeared and all is good for 3 weeks running.

I have a 1987 caprice clasic with a 305 v8 2 barrel that I have to pump the gas pettle to keep it running. could this be the carb or the fuel pump?


this problem is the carburetor which probably has dirt in it plugging up the circuits or a stuck float and when you push on the gas pedal you are supplying fuel through the accelerator circuit.it can be rebuilt or you can buy a rebuilt carburetor,but note you don`t know how long a rebuilt carb has been sitting on the shelf there by it may have dried out gaskets and accelerator pump,and be in worse shape than you own carb.

I have a 1984 Dodge d150 4x2 truck. I was driving down off the highway and i lost all power. i thought it was the fuel pump, i replaced it and gas flowed better. i started to drive again and i lost power...


have you checked for spark? check all the leads going to the coil from the battery and from the coil to the distributor, if any are loose or faulty it will cause you to lose all power, also check the terminals.

I have a 1984-85 holley 4 barrel and it has


Electric fuel pump most likely has too much pressure for the carb. AFAIK, the Holley 4150/60 & 4165/75 should each demand the usual 4.7-5.3 PSI (4.7 @ idle, 5.3 @ max RPMs), so even the Holley red pump would need some restriction from a regulator. If you want this to be adjusted to its best efficiency, you need to have a fuel pressure gauge installed temporarily, if not on the regulator like I have on my Scout II. FWIW, the regulator I have installed is the Mallory 4307M from CenturyPerformance.com, Summitracing.com, Jegs.com, etc.

http://www.malloryperformance.com/pdf/4307M.pdf

A bad Needle & Seat will do this also, or debris stuck between the Needle and the Seat. This is where light tapping on the bowl helps, but it's best to run the fuel out of the bowl a few times and then the volume flow, or quick filling of the bowl, should loosen up the debris.

You also could have set he fuel float too high. What model carb, the ones I mentioned above (AKA Holley Modular Carbs)? If so, then Holley's site has a tech center & instructions on setting the float(s). www.holley.com

Set the floats carefully and slowly/gradually. Make sure the lock screw is always loose enough before turning the adjustment nut. If you strip out the bowl's threads on an older carb, you'll beat hell finding a replacement. 1/12 turn = 1/32" of fuel height IIRC. You set the fuel level, with pump running (wrap a rag around the carb so gas doesn't leak onto the manifold!!!) so the fuel is just starting to dip out of the "peep-hole" in the side of the float. Removal of the peep/seep-hole screw/plug is necessary first. Clockwise rotation of the nut lowers fuel level IIRC and counter raises fuel level. Again, please check their website. Most people get discouraged when dealing with the Holley Modular Carbs, but they are the simplest and the best carbs on the market. Even if 30+ years old.

Old chevy 235 six cylinder, when cold it falls on its face


Question, does it stall, or bog? A few things come to mind. You say the carb. is new, what is the cfm of the carb.? Could be too much carb. for the cam. It could be a problem with the accl. pump on the carb. dumping too much fuel on take off. Have you checked the fuel pressure at the carb. also? You say you checked the timing and vac. advance, but is the timing set high enough? Usually this is a sign of too much fuel being dumped. If you have the chance, try another carb. Let me know.

1987 dodge ramcharger is leaking fuel from carburetor, is there a kit to fix the carburetor?


Yes, check at local auto parts store, but they may have to order it, seeing how everything is pretty well fuel injected now. Look for a tag attached, or at least some numbers, make of carb, such as holley or carter, 2 barrel or 4 barrel etc that they can use for reference.
