Could be Power Head Damage- Maybe you should try removing cylinder head and have a look.

Rattles before stopping usually aren't good.

Can you pull the manual start - does it still only give 3/4 turn?

I don't understand your fault description.

Does the prop rotate freely in neutral?
Does the engine rotate freely with the plugs removed?
Although you don't have a pull start cord fitted permanently your engine will be able to fit a rope round the flywheel for emergency starting.

That should at least help you split the problem into three different parts - gearbox/transmission, powerhead, starting system.
