How do I start the engine on my Ariens Sno-Thro Classic 24?

To start the engine, turn the fuel valve to the 'on' position, insert the engine key and set it to the run position. For cold engines, press the primer bulb three times before turning the choke control knob to 'on'. Then either press the electric start button or pull the recoil starter handle firmly with a rapid, continuous full-arm stroke until the engine starts.
