I'll chime in. My two cents is that all it is would be your clutch cables out of adjustment and will not press the starter plate with enough force to press the clutch into the bell for starting. This seems to be your issue having said your cable and screw thingy are jacked up. There's no way in hell you broke that pedal chain in the case. Do not disassemble that engine. It's fine. Hell I'd send you a turn key NOI to slap on there in return for that case.
