The PHBG is a really great carburetor for the more advanced tuner. It helps you squeeze extra horsepower out of that expensive speed kit you just installed. This carburetor is a BS style, left side controls and spigot mount. The Race version gives you a touch more ease of access with a screw on Carb top, so you can change throttle slides, and adust your needle settings without removing your carb from your Ped. It also has an easy access bolt on the bottom of the float bowl for easily changing your main jet. Oh, and its powdercoated black. How cool is that?
A little lesson on PHBG carbs. The first letter after the numbers: A means clamp on type mounting, B means rubber mounting, other letters were produced for specific applications and follow no rules The second letter is S for left, D for right as it refers to the side on the carb. where the mixture and throttle stop screws are. main jet = 75idle jet = 45 starter jet = 60 slide = 30 needle = W9 atomizer = 262 AN
