Solution
Check spark. Remove spark plug. Reattach the spark plug
cap and lay spark plug on metal cylinder. Pull the starter rope
and watch for spark at spark plug tip. If there is no spark,
repeat test with a new spark plug.
Push primer bulb until bulb is full of fuel. If bulb does not fill,
primary fuel delivery system is blocked. Contact a servicing
dealer. If primer bulb fills, engine may be flooded, proceed
to next item.
Set the choke lever to the FULL CHOKE position. Squeeze the
trigger and pull the rope repeatedly until the engine starts
and runs.
NOTE: Depending on the severity of the flooding, this may
require numerous pulls of the rope.
