VW T1, T2, Beetle, KG | Idle Jet 47 'Weber' ICT / progressive, (primary)

This 47 idle jet determines how your engine idles in Weber ICT carburetors with progressive linkage. It is located in the primary circuit and controls the fuel supply when you release the accelerator pedal. Wear to this jet will be immediately noticeable as rough idling or irregular behavior. Clean this jet when your carburetor is disassembled anyway, as dirt in it causes annoying gaps in your injection schedule. Combine this with a new standard throttle slide or injection tube if you're already working on it.
