If he didn't remove the valve could he have gunked up the valve with Moly paste? Bryan
MOLY in a pneumatic pump tube!!! Who told you to do that! OIL only. I suggest you clean the tube out ,deburr and smooth the lever piston roll pin holes in the front of the tube and even the long slot on the indside, so the new piston cup seal you will be needing doesnt get a cut in it from the burrs! IF you take that valve out be careful to line up the transfer port seal, and valve hole, to the barrel port --PERFECTLY or you will lose power there.
