SOLUTION
Clean or replace spark plug. Reset spark
plug gap. Refer to Spark Plug Replace-
ment earlier in this manual.
Push primer bulb until bulb is full of fuel.
If bulb does not fill, primary fuel delivery
system is blocked. Contact a qualified
service center. If primer bulb fills, engine
may be flooded, proceed to next item.
Set the start lever to the RUN 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 Air
Filter earlier in this manual.
Contact a qualified service center.
Clean or replace spark plug. Reset spark
plug gap. Refer to Spark Plug Replace-
ment earlier in this manual.
Turn idle speed screw clockwise to in-
crease idle speed. See Figure 17.
Clean threads and lubricate with grease
- if no improvement, replace the spool
retainer.
Cut tall grass from the top down to
prevent wrapping.
Operate trimmer at full throttle.
Drain lubricant and refill with correct
amount of 10W-30 engine lubricant. See
Adding/Checking Engine Lubricant
in the Operation section of this manual.
This is usually caused by storing the unit
for an extended time with the engine in
an upside-down position. Remove and
clean the spark plug. Drain the lubricant
out of the spark plug hole, then reinstall
the spark plug.
