CAUTION
The 1/8” NPT x 1/4” hose barb fitting that is
installed in the mixer housing uses a specific
machined orifice size through the fitting. This
orifice fitting is part of the mixer assembly and is
an integral part of the MI-07 control. If this fitting
is damaged the mixer will need to be replaced.
DO NOT replace this fitting with a standard hose
barb fitting or use a drill bit to clean out the
fitting passage way.
NOTE : A plastic O-ring spacer and an O-ring are
inside the mixer/adapter assembly. Be careful not to
lose these items when removing the assembly from
the throttle (Figure 31).
