    I have a 2 stroke 66/88cc bike and I can't figure out what's happening to it. It will not start but it sparks. I cleaned the carberator and replaced the spark plug and also the spark plug wires. If you can help me in anyway it would be appreciated. Thank you.

    You may need to provide more information, are you getting compression? after you crank it a few times is the plug wet? does the bike try to start, splutter and die?
    Assuming your kit is "standard," you have installed it correctly and you are getting fuel into the engine I would suggest playing with the mixture by moving the E clip on the needle.
    This has been a fairly common cause of failure to start in kits I have installed/worked on for friends.
    If it still doesn't start its time to start searching the threads..

    Is the magnet installed correctly?

    Try removing the kill switch from the circuit. Sometimes they are defective. Or I've pushed them while trying to start the engine. There is a no start guide in the 2 Stroke section of the forum that maybe of help. Just remember, you need fuel, air and spark for the engine to run.

    Good Luck,

    i.e. Make sure fuel is getting to the cylinder.

    Also check that your clutch isn't slipping. And read a lot on this forum.
