Well this started as gas going out the air box side of the carb all the way around in that hose and dumping gas all over the machine. I took the carb apart, cleaned it well and put it back together. I then adjusted the valves to make sure everything was kosher. When I took the cap off the bottom valve I was greated by 1/2 pint of gas with a little oil in it. So after adjusting valves and putting everything back together I changed the oil. Started it up and rode it for about a half an hour. No more gas spewing out of the air box hose. Let it sit overnight and went to start it. Wouldn't start, lifted the compression release and it started. Smelled like gas coming out of the exhaust again. What should I check? What is letting gas get into the cylinder?
