I was wondering if this would work this way:
Take a 4 stroke 2 cylinder or 3 cylinder (under 1L) and put modified
head with reed valves and use external oil pump to pressurize engine's
oil passages for lubing purposes. Spin engine say 200 to 300 rpm for
noise control via series of pulleys and standard 3/4 or 1 hp motor.
Yes, the modified motor will have flywheel to dampen shocks to keep
lights less flickery. Only to pressurize air tank to 100PSI, still
one stage through.
This is exactly what I can do when this oppority comes up and easier
to rebuild with standard parts instead of trying to deal with unusual
stuff.
Lets bounce off ideas & comments.

I've heard of (never seen) v-type engines with one camshaft replaced
and the injectors/plugs of that side disabled. One side runs the
engine, the other pumps air. Both share a common intake, but need
separate exhausts. I believe it's fairly important that if the
crankcase vents into the intake make sure it's on the engine side as
pumping compressed gas or diesel fumes could be hazardous. Or just vent
to the atmosphere.
With a detroit diesel 2-cycle v-8 or v-6 diesel it would be really
easy--just remove one side's fuel lines and injector rack, retime the
camshaft so the exhaust valves open at the top of the stroke, and remove
the injectors' guts and weld 'em shut. Might have a vibration issue
with the balance weight on the cam gear being out of phase.
Not exactly a small engine, though. (:
You could probably screw a check valve into the spark hole of a chain
saw engine. If you close up the transfer ports the exhaust port will
become the intake, the spark hole will be the outlet, and you can put
some oil in the crankcase for the bearings. That would be little.
