OK grumpy just did the thumb over the exhaust port,[Censored] near scared the poop out of me.Wasn't quit expecting it to be like that.So yes it blew my thumb off.Installed the choke lever however due to it coming of a wiper sniper it didn't fit correctly,so I can't put the air filter housing on with it in.However I did try to start it using the choke in the correct manner,still no go.So took choke lever out and put it back the way it was.So I still don't know why it won't go.HELP!!!!
