This lift has a hard start condition. Once is starts and warms up it runs fine and will restart. Another tech replaced the regulator before it came to us. When warm the fuel pressure is a steady 3 - 3.5 psi. When starting cold it is 10+. The mixer assy and the lock off valve was replaced with used assy. I'm not a fan but in this case it did show that there was no change. I'm new to LP and I need some help and direction.
