TROUBLESHOOTING
Possible Cause
No spark.
No fuel.
Engine is flooded.
Starter rope pulls harder
now than when new.
Engine requires
approximately three minutes
to warm up.
Carburettor requires
adjustment.
Check oil fuel mixture.

adjustment.

Not enough line on spool.
Line is worn too short.
Line is tangled on spool.

damaged.
Solution
Check spark. Remove spark plug. Reattach the
spark plug cap and lay spark plug on metal cylinder.
Pull the starter rope and watch for spark at spark
plug tip. If there is no spark, repeat test with a new
spark plug.
Push primer bulb until bulb is full of fuel. If bulb does
not fill, primary fuel delivery system is blocked.
Contact a servicing dealer. If primer bulb fills, engine
may be flooded, proceed to next item.
Remove spark plug, turn machine so spark plug
hole is aimed at the ground. Move choke lever to
"OPEN" and pull starter cord 10 to 15 times. This
will clear excess fuel from engine. Clean and
reinstall spark plug. Pull starter three times with
choke lever at "OPEN". If engine does not start,
move choke lever to "CLOSE" and repeat normal
starting procedure. If engine still fails to start, repeat
procedure with a new spark plug.
Contact a servicing dealer.
Allow engine to completely warm up. If engine does
not accelerate after three minutes, contact a
servicing dealer.
Contact a servicing dealer.
Use fresh fuel and the correct 2-cycle oil mix.

speed.
Lubricate with silicone spray.
