Having said that I have had some success with sizing the action centers with alcohol and water, as John Formsma suggested. I use a higher mix of water to alcohol, a 50/50 mix and find it works best on the Wurlies if you let it sit overnight in your shop. I use a syringe and a long needle and inject the mix into the bushing although I have also used Q-tips soaked in the solution then touched to the offending action center. I then check them for movement the following day and if there are stubborn ones, re-treat them and dry them with a blow dryer. By the way this is most common on 70's era Wurlies because they got the bright idea to start making their own actions then and pinned them all very tight. They also, on some used a "finished" pin, it's actually rounded at the ends similar to the top of a balance rail pin but most of those were from the late '50's and 60's FYI I bought an 8oz bottle of Protec about 5 or 6 years ago and still have 3/4's of it. For most things IMHO I find it to be a temporary fix that eventually can cause more trouble than doing the repair correctly to begin with. Mike -- I intend to live forever. So far, so good.
