I don't change my carb jettings from running nitrous to running without.[/quote]
I dont either i was talking about changing the jets in my fogger nozzles on the fuel side.
So your saying to run 2 complete fuel systems and to run the engine on alky and keep the nitrous on gas, i had 2 fuel systems but it was because i had junk holley blue pumps and one would not supply enough fuel to run both the engine and the spray so i put a blue pump on both the bungs on the fuel cell one to carb and one to nos it worked ok if you could only depend on the pumps to work :x , went to a magna fuel and never had a another problem
