what I don't understand is.......you were able to pedal the bike with the clutch lever pulled in, but it stopped you when you released the lever.
that tells me your clutch was working properly. that leads me to believe your piston is stuck. since it wouldn't turn over, even with the sparkplug out.

"Ok...I just tried riding.
1) With spark plug in...rode it with gasline on until 10 mph..then released clutch...rear tire and motor chain locks and skids to stop
2) Took spark plug out...rode it with gasline until 10 mph...released clutch...rear tire and motor chain lockd and skidded to stop "

"1.) Excessive carbon on the plug is from too much oil in the fuel/oil mix. That same carbon build up is on the piston too, if really excessive it could lock the piston but that would be extreme.
2.) From what you are explaining, the problem is not with the fuel/carb/ect.
Sounds like one of two things-the engine/piston is seized or locked up for some reason "
