What's in the Box


If you are like us, you really don't like pulling the carbs off to change jets over and over...These adjustable main jets will make life a little easier and get your car running right, a lot faster. Simply screw in the place of your jet well plugs and turn clockwise to lean your high speed mixture and counter-clockwise to richen the mixture. Mixture changes can be made while the engine is running and without taking the top off the carb. This new design lets the adjustable jets set closer to the carb so they will work on multi-carb manifolds, even if the carbs are touching each other.

Holley 94 adjustable main jet kit features stainless steel needle, lock nut and brass body. We also include a set of large jets (.059) and a set of extra O-ring seals if ever needed. Jets come with Teflon sealing washer and Viton O-ring seals.

  • Lean your engine for altitude changes
  • Get your exhaust temps balanced
  • Get your plug color just right
  • Give your hot rod the best tune up she's ever had

Fits Holley 94 - 2100 - ECG - and other 3 bolt Holley carburetors. Sold as a PAIR.
