I think we are saying the same thing 2 ways. With the larger squirter you will get more gas in the shot (out of the squirter) and the bypass controls the total amount of fuel available. So with the larger squirter, the entire accel pump will last a shorter time (i.e. - duration).
who knows - maybe I'm totally off. Just my idle ramblings.
When in doubt - take your car to Jim Inglese and have him tune it. He did wonders for me. Runs great after 7 years of fiddling myself. I got pretty close, but he got it right.
