First, check your ignition timing. It should be 30 - 32 degrees advance at 3000 rpm.

Do a road test to see if the hesitation is still there.

Second, adjust your mixture screws. Run each one in until the engine begins to stumble, then back it out 1/4 - 1/2 turn til the engine smooths out.

Do a road test to see if the hesitation is still there.

Three, for whatever carbs you have, research how to adjust the accelerator pumps and start by turning each one in 1/2 turn at a time with a road test in between. If you go more than 2 - 2-1/2 turns each with no improvement, then there's something else going on.

When they were rebuilt, did the rebuilder install different/larger venturiis?
