Here are some steps to follow when your engine will not start:
Is there enough fresh gasoline?
Remember...your unit uses UNLEADED fuel only.
Is the fuel valve on?
Be sure to turn it all the way on.
Is the ignition switch in the "on" position?
Is there enough oil in the engine?
Is it filled to the "FULL" mark on the dipstick?
Is the low oil shutdown switch activated?
Air can get trapped in the switch during oil filling, rocking the equipment from side to side corrects this situation.
If you are still unable to start your engine you will have to contact a your engine manufacturer for assistance.
