Understanding timing.

[MoparNorm]

The pump itself is new so I'm sure its not an issue with a worn or damaged cup.

I could try to re adjust the pump but before I do that I am wondering if the problem could be from having it leaned out to much, ( 3 turns on idle screws) and then having it hesitate when I take off.

Of all the adjustments I made on the carb, the one I least understand is the idle screws. I started at 2 turns out, turned them both 1/4 turns out until it did not increase the RPMs any further and left them at that point, which happens to be 3 turns.

Is this the right way to set the idle adjustment ? or am I barking up the wrong tree in thinking it could be the problem with the hesitation ?

another thing that confuses me is why the hesitation only happen sometimes ?

Use the vacuum gage to determine the turns, not the turn count.
