TROUBLESHOOTING
1. 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.
2. 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.

plug hole is aimed at the ground. Move choke

engine does not start, move choke lever to
“CHOKE” and repeat normal starting proce-
dure. If engine still fails to start, repeat
