Engine full of fuel and seized up
McCabe-Thiele (Ted):
Having followed this post with interest I am none the wiser yet as to what the cause was - have I missed something?

No I'm not sure I am either. Like I say at the start of this page once the starter gear was removed everything freed up. Putting it back on and everything is still free, the crank spins nicely, even keeps turning on its own with a push, I could barely move it before. Putting the rods back on as Trigger suggested and it still all turns nicely.
As I say my only concern was I'm not sure if that gear is mean to be able to move latterly on the shaft a bit which it does now. I have nothing to compare it to and nothing looks wrong.
I'd have been much happier finding something broken but not sure what else can be done.

Put the alternator rotor on temporarily(i.e. bolt not tight) then see if it wobbles when crank is spun, i have seen the taper end bent

No wobble. Checked with fixed point on the case, not that accurate, but nothing obvious.

Like I mentioned at the start it was probably that the petrol washed every bit of lubrication out of the engine and made it impossible to turn. Now it's re-olied everything is fine. But ensure on reassembly that every single part is cleaned and oiled and carefully checked.
