This is my first post, so I am not sure if this is the right place. I just purchased an 01 Hus FC470 and I can start it with the choke on and when I go to turn the choke off, it dies immediately. The only thing I have done so far is clean the air filter and check the oil. I have not checked the valves yet because I am not familiar with how to do it yet. I let it Idle for about 1 minute with the choke on and I think it should be warm enough but it just dies. I have tried to gradually release the choke and it just goes from idling (a little high like normal when a choke is on) to dead engine. I don't know how it ran before, I bought it blind. Any help would be appreciated.
