Ok. 77 Maxi. 70 kit on it. 15.15 sha. 72 jet. Thing ran fine. Sat in my basement for a month. I took it out yesterday and tried to start it and it felt like my pedal was a rock. Got it "started" today and it threw up a ton of fuel from the exhaust. I put a new plug in and I still can't get it to start. Any ideas?
