I am getting a powertorque going, the reason it stopped was starter. I am just going to do a decoke, rings are good.
But that starter was hard to unloosen. I tried as in manual, hold nut in vice and use spanner , wouldn't move. I put a socket in the vice and it held the nut much more securely and used two spanners to loosen the nut... worked.
