The starter lever on my T120 does not engage until it is almost horizontal. Apparently there is not enough motion left to start it, because it just turns over weakly when I kick it the rest of the way down. Whatever it is happened while I was riding, because it kicked over fine when I started out, but wouldn't fire after I stopped to fill up. I coasted it down a hill, got it running, but it's never run again. Any ideas?
