Possible Cause
1. No spark.
2. No fuel.
3. Flooded engine.
4. Starter cord pulls harder now than when
new.
1. Check lubricant/fuel mixture.
2. Air filter is dirty.
3. Spark arrestor screen is dirty.
1. Operating the product at part throttle.
2. Check lubricant/fuel mixture.
3. Air filter is dirty.
Solution
1. Remove the spark plug. Reattach the spark
plug cap and lay the spark plug on the
metal cylinder. Pull the starter grip and
rope and watch for a spark at the spark
plug tip. If there is no spark, repeat the test
with a new spark plug.
2. Push primer bulb until the bulb is full of
fuel. If the bulb does not fill, the pri-
mary fuel delivery system is blocked. If
the primer bulb fills, the engine may be
flooded. (See next item.).
3. Remove the spark plug. Turn the product
so that the spark plug hole is aimed at the
ground. Make sure the choke lever is set to
RUN
and pull the starter grip and rope 10
to 14 times. This clears excess fuel from
the engine. Clean and reinstall the spark
plug. With the trigger fully depressed, pull
the starter grip and rope 3 times. If the en-
gine does not start, set the choke lever to
FULL
and follow normal starting instruc-
tions. If the engine still fails to start, repeat
the procedure with a new spark plug.
4. Contact a qualified service center.
1. Use fresh fuel and the correct 2-cycle
lubricant mix.
2. Clean the air filter.
3. Clean the spark arrester.
1. Operate the product at full throttle.
2. Use fresh fuel and the correct 2-cycle
lubricant mix.
3. Clean the air filter.
