Air jets (also called air corrector jets) control how much air is allowed into the emulsion tubes, which has an effect on high-speed mixture. Weber air jet sizing nomenclature refers to the flow rate in hundredths of a millimeter (0.01mm). A 150 air jet, for example, flows the same as a perfect hole with a 1.50mm diameter. Larger numbers make the engine run leaner at the top end.
This air jet style fits Weber 32/36 DGV/DGAV/DGEV and 38/38 DGAS/DGES/DGMS carburetors. Jets are sold individually.
Also fits Weber ADF, DARA, DCN, DFAV, DFEV, DFI, DFM, DFV, DHSA, DIC, DICA, DIR, DMSA, ICH, ICT, and 3-barrel IDA / IDS / IDT / IF3 carburetors.
Fits genuine Weber carburetors only. Many look-alikes, licensed copies, and knock-offs will not accept Weber jets.
