I tried priming my oil pump tonight on a 235. Used the screwdriver trick and opened my the beehive filter along with removing the valve cover. I felt the "jolt" of the drill and saw the oil moving in the beehive filter. Closed the filter and continued, no oil at the rocker arms yet either. Turned the engine and repeated...no luck either. I guess I could try running the engine as noted by "atomarc" to see if I notice anything.
