I just started refreshing an engine. Two seasons and about 26 hours on it.
Unlike the lump in the Volvo, the block is quite clean, and initially I'm using kerosene as a degreaser/solvent.
I won't hot tank this engine and I still haven't decided whether I will break it down far enough to wash the block or the head. If I hone the cylinder bores, however, I might need to.
