Thats good to know I didn't realize that. I recently has a fuel solenoid stick open on my cheater kit. The only thing that happened was a rough surging idle. I took the carb apart cleaned it checked timing etc. etc. I was at the end of my rope. Then I opened my 1 gal fuel cell and it was almost empty! Engine vacuum at idle had sucked my 112 octane right threw my fuel pump right into the plate. I was surprised how much vacuum could be pulled threw those tiny holes 8-[COPO 572 said:If the nitrous plunger is swollen and not allowing the expected amount of nitrous into the mix, you will run extremely rich. Basically you will have a gas solenoid squirting in extra fuel and no extra air (or nitrous) to go with it. This is rich my man!!
If I remember correctly, when I took the nitrous solenoid apart, the plunger would not only be swollen, but it would be wet with fuel. I fixed the problem by changing the bends in the nitrous line so the fuel could not get into the solenoid.
no stutter - no backfire - the one thing i can think of is the bottle presher. ill be getting a blankit.DFWMalibu said:did it stutter at all...
dead hooked no slip, im getting good fuel flow at 6. the plate is in right (that was the first thing i cheked) it happins.Ed Cannon said:Yep something is definitely wrong, my old junk picks up .6 on a 100 shot. Are you spinning bad out of the hole. I know I lost 60ft times on spray until I changed to Hoosiers. Is your plate upside down? Sounds stupid but Ive seen it happen. Did you check the flowing psi of the fuel or just dead head? You need to check flowing psi, it should it be set 6 psi. Some people set it a little lower.
both solenoids are brand new and i dont have the hard line's i upgraded to the braided line's, there both angled out from the plate down and up to the noids.COPO 572 said:I sprayed my last car and had a problem that kept cropping up. This was an NOS Cheater system, so it may or may not apply.
The solenoids have a plunger and seat type arangement. The plunger actually only lifts about an 1/8" or less when activated. If I remember right, it was somewhere in the neighborhood of .060". In any case, gas from the carburetor would end up in my hard lines leading to the solenoids. Believe it or not, the seat material on the NOS plunger is not compatible with gasoline! The rubber material of the plunger would swell up so much from contact with the gas that when the solenoid was energized, the plunger would not actually lift off the seat. It was effectively closed or near closed all the time.
Might be something to consider from an old nitrous junkey.
