O.S. Needle #7G/#7D/#7H

Tower Stock# OSMG7064  •  Manufacturer Stock# 29081952
Notes from our tech department:
The needle valve is used to adjust the fuel/air mixture going into the carb.
This is just the needle (and NOT the entire needle valve assembly), the set
screw for the needle and the O-ring that goes between the needle and the needle
holder.
