This idle jet holder has a 4mm hole to accept the Weber 32/36 DGAV Primary (Large) Idle Jet (Part No. 74409, sold separately). The body has male threads to fit the Weber 34 ICT single-throat downdraft carburetor. Sold individually; only one needed per carburetor. Does not include the idle jet.
Note 1: Some later emission-controlled carburetors used an idle shut-off solenoid to hold the idle jet instead of this jet holder.
Note 2: Fits genuine Weber (made in Italy or made in Spain) 34 ICT model carburetors only! Does not fit most copies, Asian knock-offs, or work-alikes.
