FUEL DELIVERY
Jet Needle / Needle Jet
The jet needle and needle jet have the most effect between 3/8
and 3/4 throttle opening. Some mixture adjustment can be
accomplished by changing the location of the “E” clip on the
needle. Moving the clip down raises the needle in the jet passage
and enriches the mixture. Moving the clip up lowers the needle
in the jet passage and leans the mixture. Letter and number
codes are stamped into the needle and the jet indicating sizes
and tapers (taper of needles only) of each.
Jet Needle
The jet needle tapers off at one end and the clearance between
the jet needle and the needle jet increases as the throttle valve
opening gets wider. The air/fuel mixture ratio is controlled by
the height of the “E” ring inserted into one of the five slots
provided in the head of the jet needle.
Needle Jet
The needle jet works in conjunction with the jet needle.
