Easier solution is just leave the power piston in place, and plug off the power valve it's self... Take an Old Power Valve (or new), knock the pin & guts out of it... Turn it over and pound 3/16" lead shot into it... Now put the gasket back on it and reinstall into the bottom of the bowl... Jet to application.
