This "small size" (about 1/8" diameter with a 3mm flange) idle jet is used on both sides of the Weber 32/36 DGV 5A, DGAS/DGES, DFV/DFAV/DFEV, and all three throats of 3-barrel IDA / IDS / IDT / IF3 carburetors. It is used on the secondary side only of DGAV/DGEV and DGV equipped with an idle solenoid (see note below). Also fits Weber DARA/DATRA, DFD/DFI/DFM, DFTA, DHSA/DHTA, DIC/DICA, DIR, and DMSA carburetors. Does not fit any DCD/DCN/DCO series, IDF, or IDA dual-throat carburetors. Note the unusual "necked-down" portion near the (unmetered) fuel inlet holes on the side of the jet.
Weber 32/36 DGV / DGAV carburetors in racing applications typically use a 55 primary idle jet and a 50 secondary idle jet. Sold individually. Idle jet holders are available separately.
Note: This jet is not used on the primary side of certain carburetors equipped with an idle solenoid (32/36 DGAV/DGEV or DGV). Those carburetors only use this small jet on the secondary only, with the larger Weber DGAV Primary Idle Jet (Part No. 74409) installed in the idle solenoid on the primary side.
In Weber 32/36 DGV / DGAV/ DGEV and 38 DGAS carburetors, this jet gets pushed into the Weber DGV/DGAS Idle Jet Holder, Part No. WC-52570.006 (sold separately).
In Weber DFAV, DIR, and IDA3 carburetors, this jet gets pushed into the Weber DFAV/IDA3 Idle Jet Holder, Part No. WC-52570.005 (sold separately).
Note: Fits genuine Weber (made in Italy or made in Spain) carburetors only! Does not fit most copies, Asian knock-offs, or work-alikes.
