You know better than to listen to the OP...so where is this clutch he was holding?
That is still the case. Infact, you can 'pop' the auto clutch by releasing the gear lever with it reved up.hondas in the 60's would disengage with a partial movement of the shift lever or stay disengaged after the shift if the pedal was held. in that case we are looking a little deeper
No clueCentrifugal clutch? Isn't that what's on an atc70 c70 etc?

Wouldn't move fast enough.if you have socket wrench that will go over the nut on the flywheel end of the crankshaf see if you can turn it over that way. turn it easily. pop those screw covers over the valves while you do that.
