Re: 1949 Merc 8CM engine
I've been working on a stuck engine... two pistons stuck. First, I tried soaking with things like Kroil, PB blaster, etc, starting last July. No success with that. So, I resorted to the barbeque treatment, combined with Mart's BFH that he used on his 'crusty'. Got it apart quite easily. Just light tapping. Good thing I took it apart. Dead mouse carcass in one cylinder, and second cylinder filled with nest material. (It had been left with the plugs out, for who knows how long.)
