fill, primary fuel delivery system is blocked. Contact a

Remove spark plug, turn trimmer so spark plug hole is
aimed at the ground. Make sure lever is in the open choke
position and pull starter cord 10 to 14 times. This will

cord three times with the lever at open choke position.

to start, repeat procedure with a new spark plug.

when it was new.
