Hi all. Still learning about flatheads and Holley 94s - thanks for all the great posts here and on Fordbarn. I have a 3x2 setup with Holley 94s and progressive linkage on an Edelbrook SU359 intake manifold on a 59A, bored to 3 5/16 with new pistons, 4" Merc crank, Isky jr 400 cam. The carbs are leaking with the engine off and cool - looks like the leaks are between the body and the base, as well as little between the base and manifold. Also, the main nozzles always look "wet" - I'm assuming fuel is slowly dripping out of them onto the throttle plate and them out the side of the shaft. It's also having a rough time starting (very rich), but I'll tackle that next... Here is what I've got / done so far: - Electric fuel pump running at ~2.7 PSI - Good fuel - no ethanol, ~90 octane, little bit of seafoam - Rebuilt each carb with kits from vintage speed (all surfaces looked fine) - Checked the floats in boiling water during rebuild - all fine - Checked butterfly valves and throttle body shaft - tight fit - Incrementally adjusted the float level (currently at ~1.44") (measuring when upside down, no gasket) - Ran new fuel line from the fuel log on the firewall to the carb and ensure wasn't laying against the water return hose - Sealed off the front / back carbs with block off plates and disconnected fuel line to reduce variables - Gone through a couple of power valves, not leaking (dry under it) (2.5, 3.5, 4.5) - Rebuild kit included roto-disc type needle and seat assembly, cleaned it out to ensure nothing preventing seal and tried again - Replaced needle and seat assembly with original assembly including a steel needle (with no grooves) I've run through about all the recommendations I've seen. Only other ideas are: - Disassemble and true all surfaces using 220/440 paper on glass pane - Increase the float setting further - Get a Daytona float valve Appreciate any help or ideas!
