First- I must admit that I'm not a great carb guy. The AFB's actually have not been problematic- but are way too rich. Turns my rear bumper blue. Myself, and friends are all set up with Holley's, extra jets, tune parts galore. For these AFB's- I don't know where to start- Jets, rods, whatever else- I would have to buy parts for them. Just trying to simplify vs buying a bunch of parts that I won't use often.
