    Carb identification?

    Looking around but cant find much info on it - it is a Barry Grant style carb but it is a bit different --

    Primary / Secondary throttle blades are stamped 1.75" - double pumper style carb with down legs but blue venturi tubes... is this colored for being alcohol use or ? No serial numbers that I see anywhere

    Do the venturi tubes look like they come out? Meaning you can see a slight lip to the rest of the main body. BG/Demon had one carb you could swap venturi sleeves in to make it different CFM. You pulled off he baseplate to swap them out.It also had removeable boosters to swap between annulars and downlegs.

    Unfortunately the replacement parts are no longer av available.

    That is most likely a RS Race Demon. They come in drag, blower, oval track, road race and general competition. The sleeves are removable and the blue is 825 cfm. Red is 775, green is 675, gold 975, black 1025. I have a road race RS with 775 cfm sleeves and like it. Some don't care for Demon carbs. While they share similar parts with other 4150 style carbs the flow characteristics seem to be different. Wet flow vs dry. I can send you some specs of these carbs if you PM me with your email. You can likely identify it based on bleed and emulsion sizes etc.
