The engine and pump had to run almost 30min for the pressure to come up to old pump levels. I was not sure if I was going to get up to full pressure at first. But after running awhile it did come up and so far I am very happy with my repair and at least $200 richer for not having to buy a whole new pressure washer. Thanks
My power washer turned off when I released the handle
