Is this normal ?
Engine: OS160FX (I know , I know. Another one.)
Problem ??: Head sticks to sleeve.
Everytime I break it down for cleaning I find the head is stuck to the sleeve. I seperate them, re-assemble engine using after-run oil.
Engine runs great with tons of compression. Slightly on rich side but not overly sloppy. Transition is smooth and quick after idle times of over one minute+.
But is this head/sleeve sticking normal with this engine ?
