pullo, Try replacing the start/ run capacitor located on top of the compressor under the cover, EZ to get to. Look at the specs on the capacitor and perhaps Graingers will have an economical one (Dayton) I would try this prior to taking to motor shop.Cecil, Common for the 3/4 hp 1023 and 1 hp 1423 Gast to restart the same direction they last ran. If they do not have an inline or at the glass jar muffler checkvalve that prevents air from flowing backwords this can be the new restart direction as the air pushing back reverses the direction of the non powered compressor.If a bladder type membrane (s) or just long tubing runs are being used this is a common issue.A poly 3/4 inch Brady or similar check valve keeps this from happening. The valves in the exhaust port automatically close on wob-l piston pumps so this checkvalve then not needed.The Gast 1/4 & 1/3 hp 0523 R-vane does not have this issue as much for some reason.
