Actually, I know what you mean. You have an idle, trans and main circuit. If you land on it, you pretty much eliminate the trans circuit. That flat feel should be lean spot and flooring it will jump past it. Can be an incorrect HG rating of power valve. More than likely though a pump shot that is not quite set up right. Might not be enough. Sometimes guys will adjust the pump arm too far into the swing so they are running out of shot before the main circuit is fully taking over. Sometimes it's a carb winding up with the wrong pump cam because of an experimental previous owner.

I figured it was the pump/squirter issue, never took the time to tune it out
and a 4.5 PV with 9'' vacuum at idle. and bought it new and second carb with same exact deal... the 10'' verter usually bypasses the issue
