Hello everyone! I just became a member. So thank you for accepting me.
I just rebuilt the SBN 38 carbs in my '97 GTX with genuine Mikuni kits & N&S's Everything went together well. The pop off is right around 32 on each carb. All there other tests came out good except for the needle & seat pressure tests.
After pop off (using WD40), pressure will drop to 0 in about 30 or less on both carbs. When I try to test needle and seat pressure by pulling up pressure to 10-20 lbs, the same thing happens. They will not hold pressure but there are no bubbles coming from the needle or seat.
I thought that maybe my tester was leaking so I pinched off the hose between the carb and the tester and pressure held telling me there problem isn't with the tester.
Is there something I'm missing? Can pressure bleed off somewhere else in the circuit?
Any help is appreciated!
