yup, that's the one...boring out the holes will help a little, i usually use a #3 bit...that, cleaning, and maybe using a palmer's dyna cupseal are about all i know of that you can do before either sending it off or opening up the transfer hole yourself...i know of 2 ways to accomplish it, either drill up through the bottom of the valve tube into it, then tap and plug the exterior hole, or sweat the tubes apart, drill it out, then re-solder...
the pump rod release pin is a fairly common problem, i could use a couple myself, try here:
Products or good luck at a good hardware store...i just haven't found the time to look myself
