How to Repair a Kawasaki Lawn Mower Engine
One of the features of Kawasaki engines is that they have long life and durability. When these engines begin to not perform up to standard there will be three things you need to look for. A general working knowledge of gasoline engines will help in your repair.
Items you may require:
- Ten-millimeter wrench
- Spark plug socket
- Spark plug tester
- Compression tester
- Carburetor cleaner
- Place the mower on level ground or on a table at a comfortable height and lock it in position. Remove the spark plug wire from the spark plug.
- Remove the plug using the socket. Screw the compression tester into the spark plug threaded hole. Either use the starter for three to five seconds or pull the starter rope a few times to get a reading.
- Check the owner’s manual for proper operating range. If this is below recommended ranges you can check for damaged push rods. If the rods are not damaged or you replace some and still have low compression you may want to replace the engine as it most likely has internal damage.
- Check the carburetor next. Remove the air filter cover and check it. While you have it out clean it or replace it.
- Look at the bottom of the carburetor and you will find the bowl with a small screw that holds it on. Open the screw and permit the fuel inside to drain out. Check that the fuel doesn’t have sediment or water as it comes out.
- Remove that screw and take the bowl off the carburetor. Clean it out well with carburetor cleaner. Turn the engine over a couple of times. If it will not start spray carburetor cleaner into the carburetor. If it starts then dies out replace the carburetor. You will need your ten-millimeter wrench to take out the two bolts that hold it to the engine.
- Plug the spark plug tester into the spark plug wire and clip the other end to the spark plug. Turn the engine over a couple of times and if you have a spark put the spark plug back and you should be ready to go. If you have no spark you will have to replace your ignition coil.
- Remove the flywheel cover and remove the ground wire on the bottom of the coil. Take the coil out and replace it.
