      I'd think that more likely to occur with an open burner than in an
engine, especially if you had optimized the engine (advanced the spark at
least) for woodgas. I wonder how easy it would be to run all the regular house
stuff (natural gas boiler, hotwater heater, cookstove) on wood gas? Seems like
I used to have a book that had all that info, but can't remember if I gave it
to someone or what, but anyway, at most it should just require opening up the
gas jets a bit, maybe not even that, maybe just adjusting the air intakes on
the burners.
