Actually I thought about what you said about running the engine at a slower speed.
Running that Honda engine at a slower speed wont work.
But then I got to thinking if I had a bigger engine it would.
So I found an air cooled 10hp diesel engine, its most fuel efficient at 2500rpm and it makes about 5hp at 2500 RPM.
Only problems is I already bought the Honda engine to build this air compressor and the diesel engine is $800.
The diesel engine also weighs over 100lb and the Honda GX200 weighs about 35lb.
As far as I can tell the diesel engine would burn about half as much fuel as the gas motor.
