Brent,

With the current setup I am running rich, which is why I need to change out my jet possibly the air holders. The popping that I am getting on deceleration is really not that bad.

One of my main concerns is the bypass valve in the bottom of the bowl. I would like to find out if a higher number bypass valve decreases or increases fuel flow to the pumps jets. When I accelerate hard from a stand still the motor will bog down for a second then it is fine. I am thinking if I was to change the bypass valve would I go up in number or down. If you could explain how this bypass valve work I would appriciate it.
