    So I just got a new stinger 80cc kit and decided to upgrade from the previous motor I had on my mini chopper. I got it all together, took a few tries to get it running but it was finally going.

    Engine won't start, runs only on choke and almost fully lean

    My engine barely runs with the carburetor needle set at the second notch from the top side, and runs exclusively with choke on; if the choke is lowered, the engine dies out immediately, the engine dies out as well if I roll to a stop. Do you have any idea what could be the cause? I suspect...

    How do I Fix This? The pivot barrel is flush is the problem on the other side? The length is 1 . 1/16th inch doubt if sheard off. I turn the motor over while jaming the piston stop still turned over is that normal or broken crank arm? Since I done that did it upset my timing?

    No spark, deeper problem

    Hi my name is Jay. So I recently bought this Chinese motorized bike and it ran amazing for awhile and now has no spark. I tried a new plug but with a simple spark test there was no visible spark.

    Compression

    So I'm out riding Thursday and I feel a loss in compression, felt like an immediate drop in performance 50%. So I finish the ride home and check: Seals appear fine. Gaskets appear fine. Rings appear fine. Now it won't start. What else could cause a drop in compression, when I roll the bike...
