Husqvarna 350 fuel shutoff valve location?

Update: There is some growling coming out of the engine. If I crank it a ton with the choke pulled out, I can get an occasional growl to come out.
When I press the choke in, I can get it to start after maybe 5 pulls, but then it runs crazy, super loud and fast (maybe super rich), sounds like it's about to blow or something. It'll only run for a few seconds.
