TROUBLESHOOTING
SYMPTOM:
Engine turns over but fails to start
Possible causes
What to do
1. Ignition switch, emergency cut-out
switch or tether switch is in the
OFF position.
Place all switches in the RUN or ON
position.
2. Mixture not rich enough to start
cold engine.
Check fuel tank level and check
starting procedure.
3. Flooded engine (spark plug wet
when removed).
Remove wet spark plug, turn ignition
switch to OFF and crank engine
several times. Install clean dry spark
plug. Start engine following usual
starting procedure. If engine
continues to flood, see an authorized
dealer.
4. No fuel to the engine (spark plug
dry when removed).
Check fuel tank level; turn fuel valve
on; check fuel filter; replace if
clogged; check condition of fuel and
impulse lines and their connections. A
failure of the fuel pump or carburetor
has occurred. Contact an authorized
dealer.
5. Spark plug/ignition (no spark).
Check that emergency cut-out switch
is at the ON position and the tether
cut-out switch cap is snapped over
the receptacle. If no spark appears,
replace spark plug. If trouble persists,
contact an authorized dealer.
6. Engine compression.
As the engine is pulled over with the
rewind starter, “cycles” of resistance
should be felt as piston goes past top
dead center (each piston on three-
cylinder engines). If no pulsating
resistance is felt, it suggests a major
loss of compression. Contact an
authorized dealer.
