X2, the tag is what they will want to get a carb kit, the carb itself is a 5200 but the calibration on the tag tells what mods are on the carb, maybe 100 different ones.

Any 5200, leave the idle limiter caps off. Pay attention to the choke plate qualifying setting, both on the choke cap and the drill bit size used to set the choke plate if not fully closed. Screw the mixture screw in to a light dead stop and counting the turns while doing so and start there when cranking car back up again, or 1 to 1 1/2 turns if lost. Start idle speed screw with the throttle plates both barely exposing the transfer slots or hole maybe .020" and that means setting the back barrel too. Many leave that back closed and it warps you into opening the front too much to then be too high in slots and then too rich and car won't pull right off idle.
