Ok...I have looked and searched for and answere to this one also on more sites than this....
Have a Holley 750 list 1310-3 that has a moist secondaries shaft leak when motor is shut off and is under fuel pressure (6psi max after engine is shut off or runninig). I have set the rear float 1/8 of an inch below the site window with the carb level. I know Holley's are known for this if the bushings are worn on the shaft or if it has to much play in the shaft. So i replaced the shaft and bushings and it is still doing it. I looked at the butterflies when it was shut down and I can see them getting wet, but can't tell where the fuel is comming from. Any ideas? It has had a kit put in it with all new no stick gaskets, but this is really getting the best of me as how to stop it.
Thanks jim
