Full pressure regulator has a hose to the innercooler.

One hose has a T and goes to each pair of carbs.
The other hose goes to the pressure regulator.
The other hose goes to the pressure regulator.

The hose that goes to the set screw goes to the innercooler. That hose increases fuel pressure according to boost.

Hey guys we finaly got this thing going good. Went fishing yesterday it ran stong and lots of power. I was getting 100 mph in 2 feet of powder no problem. There is just a little popping wen idling I am thinking bigger pilot.
And wen i let off from WOT and get back on it she bogs for a bit ,but I think a blow off valve would fix some off that. I would like thank this forum , BigDog05 and mbarryracing.

Even though you got it running good I would do a compression test on it just to see how healthy the engine is. After running that high on the air/fuel it could easily have caused some detonation and it could get worse the more you run it. By checking now it could give you a baseline to go by at a later date.

dans2231: I don't remember where your pilot screws are set.
If it is only popping during idle, you can go out to about 2 1/2 turns or so to richen up the idle.
If its popping during light acceleration, I would add a second line to the carb slides. Just put an extra fitting under innercooler.
When you have the innercooler off, blow into the line going to the carb slides. I would bet 1 pair is rising much faster than the other.

One more thing: Have you synchronized the carbs?
