The early '70's Midgets (at least) had an air pump that
indeed was driven by the fan belt. It bolted to the
thermostat housing/cover at the top and to a tensioning
bracket below. It was on the opposite side of the engine
(assuming you have a 1275, anyway) from the carbs. I
don't remember where the intake came from, but it pumped
the "bad stuff" back into the combustion chambers via
metal tubes which went into the head just below the spark
plugs. As I recall, it was about the size (roughly) of
the alternator. -- Dave L.
