3. Loosen the 2 brake mounting bolts, using a
1/ 2-inch socket, Fig. IA-17. Squeeze the

4. Squeeze the brake lever. When brake is fully
engaged, there is to be from 1/4 - 1/2-inch

Time the Engine (Ignition)
Equipment Necessary: 13/16-lnch Spark Plug
Socket, Feeler Gauge and 13 mm Wrench
It is recommended that the ignition timing be
checked at time of "Set-Up" and each time the
engine is serviced. I ncorrect ignition timing has a
negative effect on engine performance and can
be accountable for lighting problems.
1. Disconnect the high tension wire from the
spark plug. Remove the spark plug and
washer, using a 13/16-inch spark plug socket
and check for proper type and heat range
(Bosch W260 T1). Set the air gap at 0.020
inch, using a feeler gauge.
2. Install the spark plug and washer. Tighten to
16-18
ft.
Ibs. torque, using a 13/16-i nch spark
plug socket and torque wrench. Connect the
high tension wire to the spark plug.
3. Remove the 2 bolts, lockwashers and flat
washers that secure the fuel pump to the
recoil housing, using a 13 mm wrench, Fig.
IA-18. Remove fuel pump and lay in bottom
of belly pan.
4. Remove the 4 screws and lockwashers that
secure the recoil assembly to the fan housing,
using a short screwdriver. Just before the last
screw is removed, grasp the recoil assembly
with hand, remove the screw and allow recoil
to retract against the recoil handle mounting
bracket.
5. Check the timing, using a timing buzzer
(see Section IV - Electrical System, Ignition
Timing).
