I am pretty heavy in to scale Maytag engines, and some times they don't run as you would like. This one this picture never fails. All that is needed is about 10 lbs of air, more if you want it to go faster. I have run it as high 50lbs.and guess the speed to be over 4,000 rpm It has two 7/16 diameter pistons. The scale is 5/16 of a model #72 Maytag and as you can see runs on air. I made the casting and the machine work.
