Will not effect WOT. Vacuum closes the power valve, WOT has no vacuum so power is open suppling the extra fuel needed to overcome vacuum drop. Now with the correct power valve, the motor has enough vacuum at idle and cruise to close the power valve and stop flooding.

After you have run the car a while and shut it off for a couple of minutes do you have to crank the motor a lot to start it?
