 Check the Throttle Lever. The Throttle Lever should be in the fast (rabbit) position.
 Check for debris (hay seed, etc.) clogging the Air Filter Intake and clean out as required.
 The Engine’s Blower Housing, Throttle Linkage, and Cooling Fins should be free of debris.

Clean them following the instructions in the Engine Owner’s Manual.

 Check that the Air Filter is clean. If it is dirty, change it following the procedure in the

Engine Owner’s Manual.

 Remove the Spark Plug wire and dry the connection with a rag.
 The Spark Plug may be dirty or cracked, change it. If it’s oily, leave it out, hold a rag over

the Spark Plug hole and pull the Recoil Cord several times to blow out any oil in the
Cylinder, then wipe off the Spark Plug and reinsert it.

 You should be using fresh, clean, unleaded gas. If it is old, change it. Use a fuel stabilizer

if you keep gas longer than one month.

 Check that the Engine has the right amount of clean oil. If it is dirty, change it following the

procedure on page 20.
