Holley jets. In addition to Holley, these jets can be used on some of the early Autolite 4100 carburetors as well as the early Motorcraft 2100 carburetors and the Holley 1904 1 barrel carburetors. The later (after 1963) Motorcraft 2100 & 4100 use this jet. Includes the Holley 2100, 2 barrel carburetor
Dos not fit the 2280, or 6280 2 barrel.
Threaded end: 1/4"
Don't ruin your engine. Printed specifications for jets were printed many years before the introduction of ethanol so you need to use trial & error to get the correct jet size. Test by looking at your spark plugs. Gray burning plugs are good, black is too rich, white is too lean. Change 1, or 2 jets sizes and repeat the test.
These jet sizes assume 0-5000 feet in elevation. For 5000-10000 reduce by 2, for 10000-15000 reduce by 4.
Some Holley jets were marked using 3 digits. Example 630 would equate to .063 in our list.
Also fits these Holley carburetors.

Very nice jets. Shipped with care. Love all the supporting manuals and videos you have. Best in the business!
Not everything has been replaced by computers just yet, good to have service after the sale if needed.
I received the carb jets. Havnt installed them yet but am pleased with being able to source these rarer jets.
Works for me
Purchased to increase primary jet size in my Autolite 4100 to accommodate ethanol fuels. Seems to be working fine. Thanks Mike!
Got a cple of the 0.04=51 jets from Mike. They came in fast, looked awesome and are performing very nicely. Nice parts! Thanks
Worked like it was supposed to ,but still running rich so dropped down to .071 jets
Good quality good value
Always fast and perfect
Ordered these jets and some gaskets. Remarkably fast and cost effective shipping and great quality products!
These jets are OEM quality in fit and finish. The phone staff was courteous and efficient. However, these are pricey. I bought a second set of jets from another company for half the price, and same quality. Still a good company to get parts from though, they just need to work on their shipping prices.
