    Nozzles

    I don't know any motor that uses straight size nozzles. Every motor has lean cylinders and rich cylinders and the nozzles are usually staggered to deal with that. My suggestion would be to send the fuel system to a professional to have the entire system flowed and set up. Without knowing what your pump is flowing it's next to impossible to know what are the correct nozzles. And setting a motor rich isn't a ton safer than the running it lean. Lean burns pistons and beats the rod bearings. Rich washes down cylinders and lowers the fuel pressure to the point that the nozzles only dribble instead of spray. I think you will save money on damaged parts by having the fuel system set up by someone who has a flow bench and the experience to set it up right the first time. Dave Germain

    Backing Dave up.

    Do you have time for the car to run like sh#t ? Do you have time to keep trying others ideas? Sorry; but for very little money and time you can be alot closer to KNOWING something, not just guessing. Here in the northwest alot of us use Spud Miller. He has been known to do a fast turn around setup. Or you could go race and sit in the pits aftert first round :rolleyes:

    Spud is the man. I am older and wiser now, I like racing instead of scratching my ass, Spud gave me a great deal and turn around and then call him if there is some thing you need help with, he will gladly help. Money well spent. And if you have a 632 18d then I am sure what little he will charge is nothing to what you have in the motor, do not kill it.
