So I recently picked up a 1986 kawasaki bayou 300 2x4 from my neighbor and told him I could fix it for him. It didn't run when I got it. The last time it was run was about 10 years ago. But I forgot to ask him why he put it away. So I don't know if there's anything wrong with it. He told me that the carb had some problems. I pulled the carb out and cleaned it all up and made sure everything was in working order. Then I put some high octane fuel in it and tried it, but nothing. The carb sputtered and popped a little bit but otherwise nothing. I trie putting a bit of gas in the cylinder and start it, but still nothing. When I turn it over it sounds like its starting with no spark plug in it. But there is. I think it may be the head gasket. I will check that next, but In The mean time, is there any other things you can think of tht may be wrong with it? Please let me know. Thanks.
