Rochester 4 barrel main jets. Used on 4G & 4GC carburetors. Commonly known as the 4 Jet. There are two main primary jets and 2 main secondary jets in this carburetor. Price is for 1 jet. You will probably need 2.

To correctly determine what jet size you need in your carburetor test the current setup by driving at a sustained speed for 20 minutes, stop, pull a plug and check the color. Gray is perfect, white is too lean and black is too rich. Change your jets, then try the test again.

SPEC:
  • Thread: 28
