Guys .... about to beat my head against the wall .... again . I have a new ( 300 miles ) Holley 750 double pumper from the Carb Shop on my 482 . I have been fighting a low speed/idle rich condition for a few weeks . Week before last , I tore the carb down and found fuel behind the primary P/V in the well in the throttle body . So I put a new P/V and gasket in and everything was OK .... until last week when the problem came back . Found fuel behind the primary P/V in the cavity in the throttle body again .... and found fuel in the same location on the secondary side behind the P/V plug .
Another P/V went in and the P/V and P/V plug gaskets were changed again.
Same problem again today . Tore the carb down and checked the throttle body mating surface where the metering block mounts for straightness by using 600 grit wet paper on a piece of plate glass to see if I had any high spots . Couldn`t find any .
Fuel pressure is around 5 to 6 psi , using Holley gaskets and I`m not cranking down on the bowl bolts , just snug . I am overlooking something here ..... any and all ideas welcomed !!!
