My Scag Wb bought new a few months ago has an issue with the key on/off. It will no longer turn off by turning the key to the off position even if I fiddle with it back and forth. THe only way I've been doing to turn it off is to pull the choke all the way up and it kills the engine. Is the hard on the mover? Do I need to get this repaired or has anyone else had this problem. I had an aerator which i rented last week and it was leaned hard against the Scag in my trailer to get them both to fit. The key problem happenned after that.
