An accelerator pump is a component found in carburetors that provides an extra burst of fuel to the engine during quick acceleration. When the throttle is opened rapidly, the accelerator pump releases a shot of fuel to prevent hesitation and maintain smooth power delivery. This feature is particularly important in performance vehicles, where rapid throttle response is crucial. It enhances drivability by ensuring that the engine receives the right amount of fuel at critical moments.

What is wrong with this 1985 celebrity 2.8 V6 2 barrel It starts and idles fine but when put into gear and press on the gas pedal it feels like you're running out of gas but once above 45 MPH its ok?
I would first look at the accelerator pump in the carburettor. The accelerator pump puts a short burst of raw gas into the air stream. This gives an enriched air flow into the engine causing acceleration. To check the accelerator pump: With the engine off remove the air filter and hold the choke valve open (if it is closed). Then move the accelerator linkage to open the throttle valve and you should be able to see a spray of raw gas into the venturi. If there is no spray then you need to make sure the linkage is working correctly. If the linkage is pushing the accelerator pump down and there is no spray you may consider replacing the accelerator pump.
