Carbs need air.
I have a 1978 F100, with a 1 bbl carter YFA.
4 years ago i sent the carb to be rebuilt, it sat in the driveway for 4 years, other then the occasional start. ( 2 or 3 time a years )
I am finally back at it, it started fine, i check,
it idle nicely, but as soon as i try to push on the gas pedal, you can hear the carb trying to suck air..... like it's running out of air.
1) I moved the need for the fuel mixture, all the way in, and turn it back 2 full turn.
2) i checked with a light the timing, but i forgot to plug the advance vaccum, ( will redo tonight)
3) (i think i have all the vaccum plug right) i remove the manifold tube and plug all 6 hole, and remove the AIR pump.
4) i replace the gas, put gas treatment in the tank
5) tried a carb cleaner from the top,
thought?? suggestion ??
Sincerely
Gerald.

With the engine off, remove the air cleaner and look down the throat of the carb as you fully open the throttle with your hand, you should see two strong streams of gasoline being injected.
If there are none (or only a dribble) that points to the accelerator pump on the carburetor as a likely place to begin looking.
