    sounds like you forgot to turn petcock off and motor is now full of fuel - many times, if you can keep it running for a bit, it will blow it all out and start running normally, other times, you need to take out spark plug and pedal with the clutch engaged to blow out the excess fuel

    He means full of fuel in the lower case. ALL fuel that winds up in the cylinder has to go through the crankcase first, So if you have a bad petcock or leave it on and the float valve dont shut off TIGHT then yer gonna wind up with a case full of fuel. Always turn off the petcock and check it once in a while to make sure it's working. And while yer at it you might check yer float valve. Sometimes a little peice of crap will interfere with the needle valve seating properly.

    no spark is easy to find out - take put plug, plug it into CDI wire, hold plug in hand, pedal & see if it bite you - no bite, no spark

    99% of the time It's the COIL. About $12 on flea bay.
