Beyond motorcycles and recreational vehicles, Kawasaki also manufactures a line of small motors and lawnmower engines. When troubleshooting this Kawasaki engine, owners should check certain systems and engage in minor adjustments and repairs.

Fuel System

The fuel system one of the most important engine systems. Make sure that lawnmower's fuel tank has enough fuel, that the fuel lines connecting the tank to the Kawasaki engine are not kinked or broken, and that the air filter is clean and unclogged.

Spark Plugs

Without properly functioning spark plugs, the engine may not start or run erratically. Remove the spark plugs from each of the lawnmower's cylinders with a spark plug wrench. If any is cracked or burnt, replace it. Also set the spark plug gap exactly to the distance stipulated in the owner's manual.


Inadequate compression can stop a Kawasaki engine from starting. Remove the spark plugs again and test the compression in each cylinder with a compression gauge. OutdoorPowerInfo.com provides a listing of the minimum compression level needed for each Kawasaki small engine (see Resource). If the compression pressure is too weak, the engine may need major repairs.
