Dayton 2 stage Honda Gas Powered Air Compressor

I've just resurrected a Dayton Model BF 210 2 stage (175 psi) air compressor, powered by an 8 HP Honda engine, after it sat unused for probably 5-8 years. Engine runs great (thank's Honda for fuel shut-off valves), compressor makes good air, but the regulator/unloader control is missing it's air line and as I don't have any of the manuals anymore, can't remember where it ran too, or how it either unloads the compressor or idles down the engine.

The regulator connection starts dumping control air probably around 150-175 psi, and the tank blow-off valve dumps at 200psi. As I recall it was this way when last used, but as it was used to run a double-diaphragm air pump that could use more cfm than the compressor developed, it was not normally a problem.

I'm sure I originally purchased the compressor at Grainger's may years ago, but thought you might know how the control circuit (unloader) functions on this type of compressor and I'll figure out the plumbing.

Thanks
