Well Mark, at least I have the workshop manual for that engine, so it isn't all bad. Early examples had breaker points, later ones had electronic ignition, by the way.
As you might expect for a Honda stationary engine, it has both a fuel filter and a sediment cup in the fuel system, plus as usual the float bowl may contain all kinds of collected junk, so I'd suggest you get the fuel system and carburetor into good order right at the beginning.
