The idle jet is installed under the jet cover on the Weber DCOE series carburetor. The F designation indicates that this jet controls both air (side inlet hole) and fuel (inlet hole at the tip). The F number refers to air control, and the size number refers to fuel flow. Two idle jets are required per carburetor. Sold individually.

Note that Weber assigned F numbers chronologically, as they designed the jets. They do not follow a linear "richest to leanest" sequence. The F8 allows air in through a single 1.20mm bleed hole in the side, making it leaner than the F6 and F9 family. The size numbers do follow a linear sequence, with larger numbers allowing a richer idle mixture. The 50 size is most commonly used as a starting point when changing from one F number to another.

The F9 DCOE Idle Jet (Part No. 74822) is the next step richer, followed by the F6 DCOE Idle Jet (Part No. 74810). At the other end of the scale, the F11 DCOE Idle Jet (Part No. 74824) is the leanest we currently offer.
