No fuel.

Starter rope pulls harder now than when
new.
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 unit so spark plug
hole is aimed at the ground. Rotate the
choke dial to “RUN” position and pull starter

fuel from engine. Clean and reinstall spark
plug. Pull starter three times with choke dial
at “RUN”. If engine does not start, rotate
choke dial to “FULL CHOKE” position and
repeat normal starting procedure. If engine
still fails to start, repeat procedure with a
new spark plug.
