Carter AFB Carb

[dans70stang]

Ok, anyone have or used to run a Carter AFB carb on their 5.0 or 289? I am getting around 14 MPG. Now I have heard that in order to lean out the mixture that you have to re-jet it or check for vaccum loss. I do not know how to re-jet a carb and where might the carb lose vaccum pressure? I have replaced the spark plugs(gaped to .35), added 8mm wires, a fuel filter, and a air cleaner. Any help would be appreciated.0

here is a site that talks about jetting the afb/edelbrock. I have a 650 cfm on my 351 5-speed and 3.50 gears on a 225/55/16's and when i dont have my foot in it i figure i get about 20mpg. and thats more than my 98 expo so i have justificatioin for driving it more, 80+ a day to work

you dont always have to change the jets in a carter carb, you can change the metering rods as well, fatter for leaner. the edelbrock works the same way.
