I have a friend that is young and starting out in the excavation business. He has been trying to use a construction air compressor, the type that framers haul around to power air nailers for heavy equipment maintenance. Anyway like most people, things are tight money wise, he cant buy new and what was in the $1500 range was briggs powered and not really industrial quality. This dual stage, gas powered compressor that needs work popped up for $300. The gas power is actually a plus at this point as he stores most of his equipment in an old barn with minimal electricity. It has no fuel system but I was able to get it to pop and sputter with some old gas the seller had in a squirt bottle, but it never really ran. The engine has electric start and turns over well. The belt was loose, but I can turn over the compressor part by hand and no strange noises or anything. I know it's a gamble, but I am hoping to get it going without much problem. Anyone know how to ID the older Kohler engines? I found a carburetor number, but there seems to be a glut of china made replacement carburetors rather than a rebuild kit for the original. Not sure if this is the direction to go or not. The plan is to find some type of fuel tank, clean or replace the carb and change the oil in both the engine and compressor and see what we purchased. The seller replaced the spark plug with something "close," so I was hoping to ID the engine to look up the proper spark plug also. I was thinking if I could ID the engine, that there may be a factory gas tank that would bolt on to the engine like the smaller engines on rototillers etc.
