1.
The engine has a toss of power or does not run smooth.
2.
A change from summer to winter operation.

tor was adjusted at 80 degrees at the factory.

HOW TO START THE ENGINE
WARNING:
The electrical system has two primary
components,
an operator
presence
system and a
Select
Reverse M system.
The operator
presence
system determines
if the operator is sitting on the
seat. This system
will stop the engine when the
operator
leaves the seat.
The Select
Reverse M
system gives the operator the ability to temporarily
mow in reverse
if he decides
such operation
is
absolutely necessary and safe operating precautions
are taken. For your protection,
always make sure
these systems operate correctly.
NOTE: The engine
will not start unless you depress the
clutch/brake pedal or engage the parking brake and move the
attachment clutch to the DISENGAGE position.
1.
Make sure the spark plug wire is connected to the spark plug.
2.
Move the speed control lever to the neutral (N) position (see
Figure 16).
3.
Make sure the attachment clutch is in the DISENGAGE
posi-
tion. If the blade rotation control is not in the DISENGAGE posi-
tion, the engine will not start.
4,
Move the throttle control completely forward to the CHOKE I\1
