SOLUTION
Clean or replace spark plug. Reset spark plug gap.
Refer to Spark Plug Replacement earlier in this
manual.

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.

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.
