I was thinking the same, a tank. All compressors I've seen have the unloader built is a part of the pressure switch, So as soon as the compressor is powered up, the decompression valve is closed. Compressor wouldn't even budge if it had a head pressure of 90 psi.

I have an old 2 stage air compressor, guessing 60 years old, that has a set a weights on pulley and as the compressor comes up to speed, the weights move, and a lever closes the decompression valve on the pump. This compressor has a unique motor too, no capacitors. It's a repulsion start, induction motor. The brushes lift off the commutator when motor comes up to speed.

I'm still betting the compressor is an oil-less and my limited experience says they have a large LRA. Also betting that only half the generator is feeding the 110 outlet. So he is really only getting half the power to the compressor, not enough. He should look at the round plug for a 110 volts and a larger amp rating.

George,you are right on both counts.It is an oilless compressor and the genny feeds half its output to each half of a duplex receptacle.Found book that came with it and it can easily be changed to send full output to just the 120 v receptacle> Will lose the 220 recep,but no big deal.Will let you know what happens..Thanks very much for all of you helping out,John T I wish you happy travels and please keep sharing what you know.Thanks Butch

Thanks for the kind words. Yep what you describe I classify as a "multi wire branch circuit". On those a common Neutral serves a split duplex receptacle where Phase A feeds the top outlet and Phase B the bottom. Since the two are 180 out of phase if both outlets current were the same, the Neutral current would be zero. Unlike yours, my Onan has only one outlet, a 120 volt 30 amp RV type.

Fun chat

I have a 1927 Curtis compressor that sounds just like yours with flyweights in compressor pulley, linkage to valve on head and the repulsion start-induction run motor. Only about 2 or 3 CFM on estimated 20 gallon tank, but it just keeps on ticking! Compressor pulley looks like designed for flat belt, but motor v-belt,........ but it has worked for 86 years!

My compressor is a little newer, it has side by side v-belts. I've had to sand the commutator a few times, when it has difficulty starting. Mine is only a 1.5 hp 2 stage. Yes, it keeps on going. However, I have 3 other compressors located in 3 different shops. Biggest is a 5 hp 2 stage. George
