Engine turns over but will not start (4 stroke)

1
Check to ensure that there is fresh, clean fuel in the fuel tank.

2
Check the fuel filter, because a clogged fuel filter will prevent the engine from obtaining adequate fuel supply.

3
Check the air filter to ensure that it is not clogged or dirty. The quick way to check an air filter is hold it to a light, if you can not see light on the other side of the filter then it needs to be replaced.

4
If this is the first time the engine has been started today make sure the choke is engaged. The choke is used to limit the amount of incoming air into the engine to assist with cold starts.

Note: If the engine has been started the choke needs to be off. Attempting to start a warm engine with the choke on will cause excessive fuel to enter the cylinder and flood the engine. If the engine is flooded put the throttle control to full throttle (making sure that you do not put the control into the choke detent if the unit has the choke and throttle on the same control) and crank the engine over. This will push out the excess fuel and allow the engine to start.

5
Ensure that the spark plug boot is properly secure to the spark plug.

Note: If the mower has a few seasons on the spark plug it is advised to replace the plug to ensure the engine receives adequate ignition during operation.

If these suggestions do not solve the problem, we recommend contacting your local authorized service center.

Tip: When starting the engine for the first time of the day or after a long period of inactivity, make sure that the choke is engaged. Note that attempting to use the choke when the engine is warm can result in flooding the engine. Wait several minutes before attempting to restart if this situation occurs.
