Disconnect the throttle cable from the carburetor
by unhooking the Z-fitting at the carburetor end
of the cable. See Figure 3.5.

After the powerhead is separated from the
boom, and the throttle cable is slackened, the
housing that contains the stop switch and throttle
trigger can be separated from the grip.
NOTE: Alternatively, instead of removing the
complete powerhead and grip from the boom,
the clutch housing can be separated from the
starter housing. If this approach is taken, the
stop switch wires must be disconnected as the
two sections are separated. The throttle cable
will pull out of the starter housing and clutch
housing as the powerhead is removed. Because
of the difficulty of routing the throttle cable back
through the housings, a wire or string should be
connected to the z-fitting so that the throttle
cable can be "fished" back into place.

The throttle trigger will be released from its pivot
point, and the stop switch will remain with the

NOTE: The stop switch contacts two rub strips to
ground-out the ignition module. One rub strip is
connected to the primary windings of the mod-
ule, the other leads to ground.
