Introducing the new QuickJet manual jet adjuster by Tillotson Racing. 

 

The QuickJet adjuster fits all Tillotson HW and HL carburetors and most other brands of racing carburetors, as well as lawn and garden carburetors with standard (non-EPA) adjustment needles. 

 

The QuickJet adjuster helps you precisely set the high and low jet openings to precise locations.  Simply align the rotation arm and free wheeling guide to 0, place the adjuster over or into the needle, and turn the arm to the desired turns-open setting. 

 

The guide’s 2-minute increments let you easily and precisely set the needle to the desired opening.
