Hello XXXXXXXX,
Depending on the year and your not sure. But this is most common way
Insert the black plastic lockplate on the kill switch lanyard onto the orange engine stop switch.
It will be on the front face of the motor or on the tiller handle side.

If it ran before you pulled the lanyard out then maybe you didnt insert it properly.
Make sure its in neutral and throttle on start.
