    Alright have a Ford/Holley 94 7RT Model. I see where the gas line hooks the the driver side top near the bowl, I see where the vacuum hooks up. What is the other outlet on the passanger side bottom.

    Currently replaced my 8BA for this carb and the 8BA didn't have this outlet. Any help is appreciated and cannot find a diagram anywhere. :confused:

    The later 94s had a rear facing threaded port on the base, passenger side, that held a valve similar to a power valve, but controlled the manifold/venturi vacuum mix to the loadomatic distributor. A picture would be helpfull to ID your carb.

    That's the spark control valve port, but what's in there is un recognizable to me. The normal valve head is larger than the port and seals on the outer surface. If you are not using the stock loadomatic distributor, remove what's in there and use a standard Holley power valve plug, and also plug the rear vacuum port on the main body. If using the stock 8BA distributor, get a new spark valve. Most/all 94/2100 kits have these valves.

    These later 2100/2110s came out in '54 for the Y-blocks in cars, possibly earlier for trucks. Any '54-'56 Ford shop manual will show and explain how they operate.
