Snow blower won't shut off when key is pulled?

Type your answer here... my areins snow blower wont shut off after it turn it off what could be the issue?

Most of the time either your ground wire has broke off or the pin on the key barrel is rusty: Depending where your swith is located you have to get to the back of the key barrel to see if the wire is off there if it is not take a battery powered test light put the one end on the terminal where the wire is hooked to the key and put the other on a ground (clean bare metal) then turn the key to on position the light should be off turn the key to the off position the light should come on also try taking the key barrel out and clean spot where it sits and get some rust remover to clean it with. If this works pull the cover off your fly wheel put your test light on top of the coil and the term anal behind the switch if you get no light the replace the wire.

Hope this helps
