number 30 is stamped on the sleeve for identification. Insert
the small end of the new pilot orifice into the barrel and thread
until tight with the allen wrench.
4. Line up the notch on pilot hood to the positioning tab on the
barrel receiver and snap back into position.
IMPORTANT: Be careful not to bend or kink the aluminum
tubing during conversion. Make sure the pilot hood and orifice
