Question about Cars & Trucks
Check the float levels. If it is a holley check the power valve for a power valve diaphragm failure. (they burn from back firing) Check fuel pump pressure. replace the needle and seat assy. tighten the seat in the body properly using a fibre washer.

SOURCE: truck runs rough
Sounds like one of your chambers isn't firing. Run your car for a few minutes, shut it off then pull your plugs one at a time and see if one of them is wet. Might just need a new plug.

I am familiar with these, a manual choke carb works off of a bimetal coil in the manifold exhaust crossover on the passenger side of the intake, Make sure it is hooked up, then while the car is cold, on the rockchester carbs, use an 1/8 in drillbit to set choke. You have to loosen the three screws on the choke to set, when the choke flap, the very top one on the carb touches the drillbit, set it there and lock down screws, pump once or twice and it should start and idle, as the bimetal coil heats up it should open the top flap. if you try to accelerate before it is wam it will disconnect from the auto choke. I hope this helps if not please do not rate me at all, if it does help you fix your problem then please give me a fixya,

Try to reset the IAC valve on the throttle body it has 4 wires t it .
procedure is as follows
turn ignition key on (don't start the engine), unplug the IAC valve, turn the key off, replug the IAC .Do this 3-4 times .Then start the engine while holding the pedal down at about 2000 rpm then let the rpm down slowly till idle. Sometimes the throttle requires cleaning then redo the reset.

try blocking off the valve that connects the inlet manifold to the exhaust and see what happens ??? or just disconnect it from the inlet manifold and try that before you remove the pump to have it overhauled ,Yes we do seem a bit short of motor vehicle categorys if not a yank it doesnt exist ,and as for the spelling¿¿¿¿ DA??? pigs tails??? fire wires??looks like we will have to re invade the colonys and teach them proper queens english .The only problem with that is and thats all the english have left the UK ,Its now a third world muslim country .Anyway best of british with it ---from spain

performance of the car makes these faults to come up and undermine the working
of the engine. So to start off we need to check from the fuel tank. Check if
the fuel contains impurities and specially water. If so this can come up with
the pumping when the tank gets empty and
produce misfiring, splutter and jerks.
So a check on the fuel filter will confirm this as it will be seen, if so
remove and clean tank and change the filter. We then come to the fuel
pump/carburetor as the fuel mixing and pressure is determined in this section.
You need to have the pump calibrated if the pressure at the injector is low.
If the car
has starting problems then check these tips:

The poor performance of the car makes these faults to come up like abrupt stops or spluttering which undermine the working of the engine. So to start off we need to check from the fuel tank.

If the car has starting problems then check these tips:
Then we must check with the electrics. The spark intensity is most important .Remove all plugs to check gap and condition of plugs. The black plug indication will confirm that the performance is bad whereas a fully fired plug without deposits must be the ideal view. Check the HT coil and the HT wires, if the intensity is bad this must be swapped and checked to confirm. DO NOT CHANGE any part without a confirmation by trying with a replacement from another vehicle or friend. Finally the LT trigger to the coils must be checked be it from the platinum points or an electronic ignition unit. The voltage of the trigger must be high to give the best HT output.
Now use a strobe to check the Timing on the engine. Adjust if needed to see the TOP DEAD CENTER-TDC- mark. If there is valve noise make sure that the tappets are set properly so that the valves seat firmly for the best compression. Also check compression of engine if there is imbalance on the engine or reduced power.
