Got a little problem with the Holley Carb on my supercharged Rover V8 and was wondering if anyone could advise as I am not really knowledgeable when it comes to carbs.
The unit is a L-4776-3 6000cfm Double Pumper which came with the blower and manifold straight off another vehicle.
While the front 2 barrels (chokes?) are working fine and the rear 2 also seem to perform OK when throttle is opened up. When the engine is idling the carb dribbles fuel into the back 2 barrels and after a while floods the engine and it runs rough then stalls.
I can't see any obvious screw to adjust things so I am thinking it's not a case of something being too far open but more likely to be some sort of seal which has failed & is letting fuel into the rear barrels when they are really only meant to be fuelled when they throttle is open?
If it is what I think, can anyone advise on a company who will refurb the carb for me?
Many thanks

Holleys are sensitive to float levels, I'd have a go at that first.
Also could be crap in the chambers, but could just be the classic float level thing.
Rebuild kits are about £25, and include float needles & lots of other bits. It's not hard to do, and might be worth it if setting the level doesn't fix it, plus gives you a chance to give it a good ol' clean out.
