SOLUTION
Clean or replace spark plug. Reset spark plug gap.
Refer 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.
Clean air filter. Refer to Cleaning the Air Filter earlier

Turn idle speed screw clockwise to increase idle
speed. See Figure 9.
Drain lubricant and refill with correct amount of
20W50 engine lubricant. See Adding/Checking
Engine Lubricant in the Operation section of this

extended time with the engine in an upside-down
position. Remove and clean the spark plug. Drain
the oil out of the spark plug hole, then reinstall the
spark plug.
