SOLUTION
Clean or replace spark plug. Reset spark plug gap. Re-
fer to Spark Plug Replacement earlier in this manual.
Push primer bulb until bulb is full of fuel. If bulb does
not fill, primary fuel delivery system is blocked. Con-
tact a service 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.
