Well, after shooting half a day on the *&^%$ thing it wont pump enough air to air up a rubber chicken, but having bought it at a consignment auction I didnt expect too much. Its a Dresser 2 cylinder 2 stage V Series 300, but unlike my Ingersoll Rand 2 cylinder V 2 stage, its NOT a flathead but each head has two cylindrical removeable thingys that Im guessing are valve or reed assemblies of some sort??? ????? ????? ????? ???? It looked good n clean with no leaks and a very smoth crank feel and action and runs very smooth n quiet with no knocks or hammers nor any crank end play, IT JUST WONT FREAKIN PUMP. Anywho, the air inlet port on the big low pressure piston BOTH BLOWS AND SUCKS although seems to me due to some valves or reeds (hopefully encased inside the removable cylinders on top each head) it ought to SUCK AIR IN ONLY, being its the inlet side on the big piston side. The big pistons output, of course, has a line over to the smaller high pressure pistons input with its output going to the receiver. I want somebody to tell me (and not be kidding lol) "Yo John T, it just has a gummed or sticking reed or valve and all ya gotta do is remove those cylindrical valve bodies on top the heads n clean n free n polish them up and she will pump till the cows come home" Can anybody tell me that and be serious and give me any tips of what might be the problem (why the inlet sucks n blows, stuck valve I hope) A Frustrated John T
