1. Check fuse condition.
2. Clean corroded connections and tighten loose connections.
3. Replace wires in poor condition and with frayed or broken
insulation.

replace the faulty components.

1. Check for excessively dirty or worn brushes and commutator.
Clean using a coarse cloth (not emery cloth).
2. Replace brushes if excessively or unevenly worn.
1. Make sure the clutch or transmission is disengaged or placed in
neutral. This is especially important on equipment with
hydrostatic drive. The transmission must be exactly in neutral to
prevent resistance which could keep the engine from starting.
2. Check for seized engine components such as the bearings,
connecting rod, and piston.
1. Check for corroded connections, poor ground connection.

Electric Starting Motors
Electric start engines in this series will use either an
inertia drive, or a solenoid shift starter. Each style has
its own respective starter solenoid incorporated into
the mounting configuration. The inertia drive starters
are covered first, beginning on page 8.25, and the
solenoid shift style covered starting on page 8.31.
Starting Motor Precautions
NOTE: Do not crank the engine continuously for
more than 10 seconds at a time. If the engine
does not start, allow a 60 second cool-down
period between starting attempts. Release the
switch as soon as the engine starts. Failure to
follow these guidelines can burn out the
starter motor.
NOTE: If the engine develops sufficient speed to
disengage the starter but does not keep
running (a false start), the engine rotation
must be allowed to come to a complete stop
before attempting to restart the engine. If the
starter is engages while the flywheel is
rotating, the starter pinion and flywheel ring
gear may clash, resulting in damage of the
starter.
NOTE: If the starter does not crank the engine, shut
off the starter immediately. Check the
condition of the inline fuse and do not make
further attempts to start the engine until the
condition is corrected.
NOTE: Do not drop the starter or strike the starter
housing. Doing so can damage the starter.
Starter Removal and Installation
Refer to the Disassembly and Reassembly sections for
starter removal and installation procedures.
