I've a seeming ongoing problem w/the TR carb. The engine is a 509 CI GM type Big Block.
The problem is, while closed (idling), the secondaries dribble fuel from around the mounting
points of the boost venturis and it puddles on the secondary butterflies. The carb is a marine
Holley 4150 800 CFM, list #R9022.
I've carefully set the secondary float level w/the pump running at 4 PSI, but the engine NOT
running. As soon as I start the engine, it starts dribbling fuel again.
I've carefully read the literature on the Holley site, and I also have an HP Books Holley manual,
but I can't seem to find a solution.
Here's lots of pictures, and if anyone has ideas, it would be appreciated:
