smoothly.
(Please refer to
the engine
manufacturer’s

specific
procedures.)
⇒ Check the throttle travel and adjustment.
⇒ Is the air filter clean? If it’s dirty, change it following the
procedure in the engine manufacturer’s owner’s
manual.
⇒ Is the spark plug(s) clean? If it’s fouled or cracked,
change it. If it’s oily, leave it out, hold a rag over the

blow out any oil in the cylinder, then wipe off the
plug(s) and reinsert it.
⇒ Are you using fresh, clean unleaded gas? If it’s old,
change it. Use a fuel stabilizer if you keep gas longer
than two weeks or so.

If it’s dirty, change it following the procedure in the
