Quick Start:

)
IE:
1) Remove spark plug cap.
2) Unscrew sparkplug(counterclockwise)
3) Spray some 'Quick start' in the 'hole'. Start with '1 second' worth of spray and gradually increase.
4) Screw in sparkplug clockwise until it is hand tight. Be careful here, hand tight should be enough to start the mower. Once it is running ok, I wouldn't go any more than a 1/4 turn past hand tight. If you strip the holding thread, it will be a very costly mistake.
5) Pop on spark plug cap and proceed to start engine.
6) You may want to experiment with the choke on/off or different throttle speeds(depending on how your mower is set up).
