TROUBLESHOOTING
SYMPTOM:
Engine cranks but fails to start.
POSSIBLE CAUSES
WHAT TO DO
1. Ignition switch or engine cut-out
switch in OFF position or tether cord
cap away from post.
Place engine cut-out switch in the ON
position and install tether cord cap on
post.
2. Mixture not rich enough to start cold
engine.
Check fuel tank level and check starting
procedure, particularly use of the primer
or the choke.
3. Flooded engine
(spark plug wet when removed).
Do not prime or choke. Remove wet
spark plug, turn ignition switch to OFF
and crank engine several times. Install
clean dry spark plug. Start engine fol-
lowing usual starting procedure. If en-
gine continues to flood, see an autho-
rized SKI-DOO dealer.
4. No fuel to the engine
(spark plug dry when removed).
Check fuel tank level; turn fuel valve on
if applicable; check fuel filter; replace if
clogged; check condition of fuel and im-
pulse lines and their connections. A fail-
ure of the fuel pump or carburetor has
occurred. Contact an authorized SKI-DOO
dealer.
5. Spark plug/ignition (no spark).
Remove spark plug(s)
,
then reconnect to
spark cap. Check that engine cut-out
switch is at the ON position and the teth-
er cut-out cord cap is snapped over the
receptacle. Start engine with spark
plug(s) grounded to engine away from
spark plug hole. If no spark appears, re-
place spark plug. If trouble persists, con-
tact an authorized SKI-DOO dealer.
6. Engine compression.
As the engine is pulled over with the re-
wind starter, “cycles” of resistance should
be felt as piston goes past top dead cen-
ter (each piston on multi-cylinder en-
gines). If no pulsating resistance is felt,
it suggests a major loss of compression.
Contact an authorized SKI-DOO dealer.
