So after removing the plug shims and re-assembling the 760. I see that I must have caused something to go wrong with the plastic transfer hole from the valve to the barrel. I'm guessing I may have scratched the pump cup itself as well. In any case there are permanent leaks somewhere. I'm not going to repair it, but how does someone go about fixing a problem with the transfer port/barrel alignment in a 760 anyways?

Thanks
