After replacing all o rings including one in middle of valve with the two pointy sides. It still leaks down very slow. I noticed that went I put tilt up and took off motor I could see the oil coming up out of area around ball with spring that you can adjust. I tried putting more pressure as well as less pressure. Neither seemed to work I started out at 3/16 as told for starting pressure. I did not replace ball bearings as they looked to have no where on them. Any suggestions?:
