take out spark plug, open both the clutch & drive covers, look for where movement stops

I had a similar issue happen to me before. It turns out that a rock got stuck in between the chain and the sprocket attached to the motor. I'd suggest taking off the side cover with the clutch arm to see if the chain is jammed. It might also be that your clutch cable is loose and isn't pulling it in far enough.
