Engine will not start: | 1. No spark. |
2.No fuel.
3.Flooded engine.
4.Starter rope pulls harder now than when new.
1.Check spark. Remove sparking plug. Reattach the sparking plug cap and lay sparking plug on metal cylinder. Pull the starter rope and watch for spark at sparking plug tip. If there is no spark, repeat test with a new sparking 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 (see next item).
3.Remove sparking plug, turn trimmer so sparking plug hole is aimed at the ground. Move choke lever to “RUN” and pull starter cord 10 to 15 times. This will clear excess fuel from engine. Clean and reinstall sparking plug. Pull starter three times with choke lever at “RUN”. If engine does not start, move choke lever to “CHOKE” and repeat normal starting procedure. If engine still fails to start, repeat procedure with a new sparking plug.
