Hi guys, my generac generator model #0058240 won't start unless I manually open the lever in the fuel regulator behind the diaphragm using a small screw driver, or spraying a small amount of quick start in the mixer box. When it starts it operates perfectly in all load modes. My lp fuel pressure is 11.5 in/H2O at the outlet of the regulator, compression test on both cylinders is 210 psi, and pressure holding 210psi for 10 mins. The generac tech said the regulator was bad, I replaced it but engine still did not start unless I manually opened the lever or use quick start. Does anyone know of a test, or is there a vacuum from the intake that assist the diaphragm to open the lever to.
