Check out the tech and jetting articles to find out how to set up your AP circuit.(Accelerator pump). From memory, there is also some good info on Leak jets there.
Generally speaking, the timing of the AP squirt, and duration, set the initial engine throttle response when the throttle is snapped open. More fuel = less bogging/hesitation.
The LEAK jet controls how much fuel is allowed to pass (leak) back into the float bowl. So, a bigger LEAK jet allows more fuel to recirculate back into the bowl, hence LESS fuel to the AP squirt and to the engine.
The stock Leak jet is #50 and is good for HOT and humid conditions when you dont want much AP squirt fuel.
Check out Clark4131 and Indys jetting guides for exact starting points. Most call for a #40 leak, very cold conditions require #0 Jet (a soldered up whatever).
