what am I missing ? looks like you have it all. grimy , to be sure, but all there. clutch cable could be shot, but the clutch lifter (#7) adjustment is tricky , and I bet that's where you're getting tripped up .
also, if the bike sat for long, the clutch plates can be stuck together . fresh oil, and a few warm up/cool down cycles whilst working the clutch lever (hand control) should free it .
