Helped my off idle take off tremendously. Used a .21 with a 37 jet and upgraded emulsion tube. Very nice combo. Hard acceleration all the way to top speed.

When changing the bottom jet (35-38) and "E" tube a .22 low RPM jet allows for a perfect idle though does not fit the new generation predator carb the carb still idles nicely without one when changing the other jet!
