To set the accelerator pump on a Holley 600 carburetor, first ensure the engine is off and cool. Remove the air cleaner and locate the accelerator pump linkage on the side of the carburetor. Adjust the pump arm by changing the position of the linkage or using the adjustment screw to achieve a slight amount of play—typically around .015 inches when the throttle is closed. Test the adjustment by opening the throttle and observing if the pump squirts fuel immediately; if not, fine-tune the adjustment until you achieve a quick, responsive squirt.
the ignition timing set wronge. BAd accelerator pump in the carburetor
Depends on the engine and carb set-up as well as the weight of the drivers foot on the accelerator. I have a 1973 F 250 with a 460 and a Holley 650 carb and I get right about 7 MPG. I can get as little as 4 MPG if I drive it like it wants to be driven. Definitely NOT the vehicle to be driving around in for fun!
The timing is set incorrectly. Carburetor(s) needs rebuilding (bad accelerator pump). Firing order is mixed up. Replace or adjust ignition points and condenser.
Accelerator cable? No. Accelerator pedal set up? Yes.Looks like 2 bolts to remove the pedal clusterfrom the floorpan and then there is a bolt going through the pivot for the gas pedal.
The idle is set too high, the accelerator linkage is sticking, or your foot is on the accelerator. Most likely one of the first two.
Cruise control
To tune a 2-barrel Holley carburetor, start by ensuring the float levels are set correctly, as this affects fuel delivery. Adjust the idle mixture screws for the best idle quality, typically by turning them in until the engine stumbles, then backing them out slightly for optimal performance. Next, check and adjust the choke operation if necessary, and finally, make sure the accelerator pump is functioning properly to provide adequate fuel during throttle transitions. Always test the vehicle after adjustments to ensure proper performance.
Probably start out at the manufacturers spec and increase a little at a time until best performance is achieved. The 600 should be fine for a mild 350, but a cam with that much duration will need an aftermarket convertor for an automatic. A four speed should work ok.
I can only think of a couple possibilities; You may have a faulty fuel pump or your fuel injectors could be clogged. I would try the fuel pump first seeing that it is much cheeper than a set of injectors. One other thing you could do is check the accelerator swith to see if there is enough tension.
Idle set too high or accelerator is sticking and needs lubrication.
If you mean the one for the oil change reminder, if it has a reset button it is in the fuse panel. But just to let you know some years did not have a reset button, you use the accelerator pedal to reset the timer. If you need to do it this way you turn the ignition key on and within 5 seconds, pump the accelerator pedal 3 times and release it, then wait, the "Change Oil Soon" light should flash and go out then it is reset.
holley makes carbs for all vehicles. the manifold on the caddy is set up for the carter afb, which edelbrock used as a base for their carbs, so an edelbrock will bolt right on. this is the route i took with mine. you will probably have to get an adapter to set the holley up on the square bore of the old caddy intake. the adapter should be available wherever you get the carb. hope that helps.
