ALL Valve

"All" Valve is all 3 common control valves for a (nitro) fuel managment system - in one

Also required is the Management System - a computerized air regulator :

A Enrichment :
Black nut on top of all valve - simply delays opening of valve by adding pressure to spring - causing flow spike
B initial Gap:
Space on top of All Valve - acts like a main jet until air from regulator (ALL - Pres/Reg) exceeds 40 psi then starts to close
just like a slide valve - until reaching max set pressure then starts acting like a BDK (pressure regulator) lean out.

CC/turn = the amount of fuel going in the motor
ALL - Pres/Reg = the air pressure at ( C air line to ALL Valve ) Aprox-5 to 1 ratio of fuel pressure
Fuel Pres = preeure of fuel lines going into motor
Note - fuel pump to small = the fuel pressure should contine climbing but the fuel pump reached max flow (need bigger pump) ,
 cc/turn also flat.
