3. Flooded engine (spark plug wet when removed).
–
Do not choke. 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 con-
tinues to flood, see an authorized 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 failure 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 tether 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, replace spark plug. If
trouble persists, contact an authorized SKI-DOO 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 multi-cylinder engines).
–
If no pulsating resistance is felt, it suggests a major loss of
compression. Contact an authorized SKI-DOO dealer.
Engine lacks acceleration or power.
1. DESS did not read tether cord cap code. DESS pilot lamp blinks
once every 1.5 seconds. Engine can not exceed 3000 RPM.
–
Properly install.
2. DESS has read a different code then the one programmed. DESS
pilot lamp blinks rapidly (3 times per second). Engine can not ex-
ceed 3000 RPM.

Install a tether cord cap (key) for which this snowmobile was
programmed.
