I have a standard 66cc happy time motor that has been running fine for roughly a year. Yesterday I pedaled to start the bike, and it started normally. Then when I went to give it gas, it just revved the motor with no power going to the wheels..just as if the clutch lever was pulled in, or the chain got thrown off. Since I don't have a kill switch, I had to pull the spark plug boot to kill the motor. I did the standard troubleshooting with the pads, and with the bar and ball bearing and cable, and all seems functional. I took it back out and pedaled down the street, and it acts the same whether lever is pulled or not..the only difference is that I hear clutch chatter when lever is pulled. Seems that something internal has given way, but I couldn't really find any cross section schematics of this motor, and I don't know where to start looking. I know that the clutch is not just slipping. Can anybody offer a suggestion as to what I should look for? Does the motor actually drive the small sprocket that is mated to the larger sprocket on the clutch side? Any help will be greatly appreciated. Thanks
