Ok you got me! What is a bunt plug?
Good thing when the crank handle was on the rim of the heavy flywheel. The ones with the crank like car took some real umph. That was probably what generated the pony engine idea.

I think that was a rolled up paper about the size of a cheroot filled with saltpetre, lit then put in a plug and scewed into the cylinder or manifold, a crude form of glow plug, it would smoulder red hot for a while.
