Just finished rebuilding my first 500, a 91. Just got the cylinder re-sleeved, new piston and rings, new spark plug, checked the carb and everything. All new fluids. Everything seemed good so I took it outside and it started in about 5 kicks. But being a 500 rookie, I killed it, and now I've kicked it 100 times and it won't start again. I've waiting for an hour and tried again, won't start. It fires a little bit, but won't start. It seems like there is a lot of gas pouring out of the carb when I tip it. I think it has a 172 and 48 jets? I don't remember exactly it was about a month ago. And I'm at about 800 ft I'm searched around but didn't see anything, so thank you for any help!
