On the carburetors that I use there is a power jet.
This jet sits on the top of the air horn. The air entering the carb speeds up as the air horn tapers towards the slide. The increased air velocity yields a lower pressure. This jet is feed by a hose running into the bowl. The fuel needs to be pushed up the hose to get to the jet and into the carb.
When the velocity of the air in the horn increases enough, the pressure in the horn gets lowered to the point where the atmospheric pressure in the bowl (which is vented) can overcome the "head height" and push the fuel up the hose to the jet.
At least this is how I understand that it works. Same concept as the main jet and venturi inside the carb.
What I want to do is cap off the port going into the bowl and gravity (or pump feed) the jet.
So now instead of the fuel flow at the jet being based off atmospheric pressure in the bowl, reduced pressure in the horn, and head height between the bowl and jet....
Fuel flow would be based off the pressure in the line feeding the jet. For gravity, a couple tenths of a psi. For a pump 1-2, 3-5, 4-7 psi (what ever pump I use).
Not sure if I have a question or really understand any of this.
Trying to work out a wet N2O system for my 6Sigma Nitrous Kit.
I was trying to figure out the easiest way to introduce extra fuel. I think a solenoid in the line feeding the jet would be fairly easy. The nitrous would get injected on the other side of the slide (at the manifold pulse fitting). My other idea was trying to use the N2O stream to pick up the extra fuel and introduce them both together though a single port in the carb or manifold. I guess the way an airbrush sprayer works??? But that seems more complicated. Like I would basically have to design a carburetor????
Any ideas.
There was a thread that went into this a bit.

"added a Pvc bottle with dip tube and a nozzle with hops c9 race gas to give it a shot of fuel with nitrous and it made a diffrence in power. I sold the kart and it still has the same motor , running strong ."
