    Hello, I have a two stroke motor attatched to my bicycle, and I have a bit of a problem. I ran it for about five minutes, and then couldnt get any response to increasing the throttle... It just kinda sounds flat bbuuuaaa. As soon as I pull in the clutch, it kills the motor. Also, Ive seen some gas leaking from my exhaust (front mounted on the opposite side of the carb)... Any ideas would greatly help!

    Thanks,

    If you have seen a lot of oil or gas leaking on the exhaust maybe you are putting to much oil to the gas.

    Ive had that thought, but maybe thought it had to do with basically flooding it. It isnt to much gas, just a few drops when it shuts down

    Yeah, i think is cause of that.
    Take the spark plug out and check what colour is it.
    It has to be like coffee with milk.

    between the center electrode and the ground electrode, the literal "gap" where the spark travels

    Ok, so I took the plug out and cleaned it. It ran with a bit of hesitation. I took the plug out again, and cleaned it once more. The bike started fine, then the idle kicked up like crazy. I shut it down and lowered the idle screw, and now it wont start again! Any ideas? Could it still be my plug?! Help please!

    Also, how would I go about checking my ignition system?
