The Ford Barn

I have a ’39 Coupe that was built in the 50’s. 59 motor, Navarro heads and intake with 2 x 97’s, headers, etc. Did all of the ignition work, including new electronic distributor, plugs, wiring ( carbon wiring for electronic ) and rebuilt the 97’s completely..including removing the emulsion tubes. Engine basically runs OK ( not the best as it should ) and my problem is that it uses a ton of gas. I must be getting about 5 mpg. New plugs after an hour’s run are black & full of soot. Carbs are stock jets at .045, power valve also stock at 65. I am told to change the power valves to a higher # to decrease fuel flow. I cannot believe how this is sucking up so much gas with stock configuration carbs.. Comments / help would be appreciated…Thanks in advance.
