Description
Customer Reviews

1964 & newer models with 5/16" threaded end jets. This assumes you have a number matching carburetor. Some of the older 2100 & 4100 Autolites are much smaller. Typically 1963 and older (assuming you are 100% sure you know the year of your carb.). This type of 4100 will probably have a plastic lever going to the secondary diaphragm. This type of 2100 & 4100 jet can be found here.

Motorcraft main jets, 1100, 1101, 2100, 2150, 4100, 4300, 4350. Priced per each.

Jet Testing

To determine if you have the correct jets in your carburetor, operate your vehicle for 20 minutes at sustained speeds. Stop and pull a plug. Gray - Good, Black - move down one jet size, White - move up one jet size. Do it all over again until you get a gray plug.

This assumes your engine and electrical system is in good running order.

For moving from sea level to over 5,000 ft. reduce your jet size by .002.
