How do the Amish compress the air Grigg?
A bicycle hooked to an air compressor?
Jerry's idea of a 4 cylinder engine/compressor reminds me of a gizmo my dad had with his shop truck (a '48 GMC 3/4 ton at the time). It was a thing that screwed into a spark plug hole and used that cylinder to compress air. It had an intake check valve arrangement (so that cylinder didn't pull as much fuel air mixture thru the intake) around a central output hose connection. We used it on a job to pump up a 1/4 mile long natural gas line for a leak test. I (as the plumber's assistant) would have been there for two days with a hand pump. It could be used for airing up tires on the road as well.
