Why It Matters

If the mixture leans out past four grand where the pull should be strongest, jetting is the place to look. The 140 sets wide-open fuel so you can trim the mixture to your engine and your elevation.

Installation Notes

  • Threaded brass jet that swaps with a flat screwdriver.
  • Trim the jet size to your engine and your elevation.
