Improving acceleration using 2bbl Carburetor?

Accelerator Pump on the carb, seal gets bad.

Can get a new one. Basically gives the carb a shot of gas when you first depress the gas pedal to give it some extra fuel to get it going up off the low rpms.

When accelerator pump is wore out dried up, won't give the engine the shot of fuel it needs to get going so it stumbles to get up to rpm where it can draw fuel more easily.

Oh yes, unscrew the low speed idle jet at the bottom outside carb. Spray some carb cleaner in there and blow out with compressed air.

Reinstall low speed jet to the bottom and back out 1 1/2 turns as your starting point for adjusting fuel at idle.
