That will ruin a pump fairly quickly.... Make sure the valve linkage is free so that the valve kicks ou on it's own. If that doesn't do it, look at the back of the valve near the top. There is a set scre and a jamb nut. Loosen the jamb nut and back the set screw out 1/2 a turn at a time until the valve will kick out at idle when the oil is warm. If you don't want to do that, pay attention to the valve handles and listen more closely to the engine laboring... otherwise it's going to soon cost you some serious money.
