HC 6,Box 4 Aitkin, Minnesota 56431
Here is a picture of a Gardner air compressor I converted to a gas engine. It has a hit and miss governor, a make and break ignition, 2 x 3 inch bore and stroke.
It has plenty of power to belt up to a stubborn engine to start it.
I got the compressor from Bill Hadley, who lives in Texas City, Texas. The Collector's Network, 1989 issue, is responsible for us getting to know Bill and Ruby Joe Hadley.
