You've had lots of good advice in the various posts in response to your question. When all is said and done, however, you're going to find that no matter what you do you're going to have a nice positive lift and the hammershank will fall when you trip the jack with your finger. I've never taken the time to figure out just what the problem is with that particular action design, but from time to time you'll come across one that responds this way. Not all Baldwin actions do this, but when you come across one that does there is not much you're going to be able to do about it. So...after you do all the things all those nice folks have suggested and find that none of them work just set the jack height by running your finger across the top of the repetition lever and adjust the screw so that the jack is exactly flush with the top side of the lever. If you don't trust your finger then make a small, very flat, stick just as wide as the repetition lever and lightly drag it across the top of the repetition lever setting the jack so that your stick just brushes its top as it crosses. Don't worry, the action will work fine in actual use. Regards, Del
