CA100 Mixer Installation Steps
1.
Install the vapor fuel inlet fitting onto the mixer.
2.
Install the four mounting screws that attach the
throttle adapter to the mixer. (See Figure 32).
Torque bolts to 30-40 lbf-in (3.39-4.52 N-m).
3.
Position the mixer/adapter assembly onto the
throttle body (4), then drop in the four mounting
bolts and gently push down on the assembly
until it rests on the throttle body. Be careful not
to pinch the O-ring.
4.
Attach the mixer/throttle body assembly to the
intake manifold, making sure gasket is in place.
Tighten the four mounting bolts.
5.
Connect the wiring harness to the throttle body.
6.
Install the vapor fuel inlet line to the mixer.
7.
Install the vacuum line (2) to the mixer.

Install the air cleaner hose (1).
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).
