Description
Fits DCOE / IDF
Model F2, F7, F9, F11, F14 or F16
F7 gives richer partial acceleration and affects the low-speed part and usually works well on V8 or cars with a lot of porting or stingy overlap "lean spots", for engines with greater fuel requirements at low speed, you usually have to combine with a large air nozzle if it is too rich at high speeds.
F11 and F14 are the ones that are usually installed in new DCOE carburetors. They have a slightly leaner middle section. F11 is richer at high speeds than F14
