Default Holley 94 carb leaking ???

I have a stock 1952 Ford F-1 with the Ford flathead V8 engine. Last year I purchased a professionally rebuilt Holley 94 (model AA-1, 2100). Engine runs great. I am noticing though a slight build up of grease/grime under the carburetor on the passenger side. I have checked to make sure everything is properly torqued. I have watched and watched trying to find some leak in the carb creating this junk under the carb. I can't seem to locate the source of this. The drippings are only under the throttle side so I am suspecting leaks either from the throttle or PV.

Is this typical? Is this something I can repair?

Any input welcome, Thanks.
Fred

Could be a worn throttle shaft on that side,usually only leaks when engine is shut down. Itwill pull air in around it leaning out the mixture when running.Find an identicle base and change it with new gasket that has a better fitting shaft [up and down play].Should be just enough clearance to turn.Make sure its off an 8BA or later carb,7 or 8RT is ok too. ken ct. or send it back to the rebuilder if still on garentee and explain what the problem is.OMO. ken ct.

Sounds like the wrong power valve which don't seal. There are several PVs out there a most are wrong..Vintage Speed sells the correct one..

Can too much fuel pressure cause this? Mine leaks when running. Or, could be float height? Instructions in kit weren't real clear on setting height.

My own opinion is you used a cheap China made kit and contain many incorrect parts.Have it re-rebuilt by a competent carb guy that uses a made in usa kit.There are a few of us on here myself,charlie,ny and 52 henry all do excelent work. ken ct.
