I have a 1993 YZ 125. It hadn't run in a year or two. I got it all cleaned up, filled up and fired it up. It kicked off on the 2nd or 3rd kick but the rpms went crazy. It revved super high and took forever to come down. I killed it with the kill switch. Took the carb apart and cleaned it again. Now it won't start at all. It has spark, compression and fuel. Any ideas? Thanks for helping a newby.
