25 ymaha question

My Friend bought a used 25 Yamaha 2 stroke, its about a 2005 model, we can't kill the Motor with out either pulling the Emergency Kill pin, or chocking it down, we think it should kill by turning the Throttle counter clock wise, is this correct, if so is it just turning off the fuel, or is it suppose ground out the fireing system, can one of you help us on this, if it is suppose to ground the system out we may have a broke or lose wire, or if the Throttle is what killes it, we may be out of adjment some where,, Thanks for what ever some of you can do for us, it just wants to RUN,

That motor will not shut down just by turning the twist grip.
If you press the button that the emergency kill switch is attached to, it should shut the engine down.

Thanks <> Tonyaus<> why in the world didn't we try that, Thanks a Million, This From sure helps people like me to be able to tap into some of you Guys that have been there and done THAT,
Thanks Again
