Default Re: helpmy bike rolls with the clutch engaged and this is not normal

Silver Flying Horse 66cc/80cc
NT Carburetor
44 tooth 9 hole sprocket on coaster brake hub
415 chain

Yes the piston does turn over but I am pushing the bike with the clutch engaged!
As we all know the back wheel should be sliding not rolling while clutch is engaged.

The first check I made the day following the engine falure was inspection of the magneto. Reason being that on a previous breakdown the blue wire was the cause, I re soldered it for a simple fix. Unfortunately this was not the case for my current problem, I found that the wrappings of the magneto were soaked with oil. I dried it off fastened back in place, is this part of the problem?
I inspected the piston for poss hole in piston as the cause due to loss of compression, piston intact but extremely blackened, also inspected clutch pads removed all 15 cleaned entire area found that the reverse side of pads had more abrasive reassembled remaining clutch spring, clutch plate and flat lock nut with tiny keeper screw.
