Re: Motorcraft 2100
The only flow you can adjust is the flow of fuel by changing jets, not cfm's. The venturi's cannot be "adjusted", unless you are talking about specialized machine shop work. No need to adust the venturi's, the 1.08 is the size of the venturi's and that is a nice size for a 258 and the cfm's it requires. Too big a carb causes poor throttle response. Order the carb for a 304 AMC v8.
84 CJ7, 258, HEI, M/C 2100 carb, 5 inch lift, RS9000's, 33x12.5 BFG M/T's, Lockright, full cage & belts, Xenon flares, AMC 20 1pc axles, GM dual diaphragm brake booster
