Remove spark plug(s) then reconnect to spark cap. Check
that engine cut-out switch is at the ON position and the tether

–
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.

–
As the engine is pulled over with the rewind starter, “cycles”
of resistance should be felt as piston goes past top dead cen-
ter (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.
