Lean Stumble.
Possible causes, NO or not enough accelerator pump shot.
Some fool puts a screw in the mechanism on the vac secondary linkage to force them open.
Lean idle mixture.
Low float level.
There are more..

If you are not leaving from an idle, you're using up a lot of pump shot.

Another thought if you run a vac advance be sure its on the right port.

Is this a new problem that started out of nowhere, or is it a result after swapping a few parts?
