Hi David, How old is the instrument ? And does it look like original parts are still there or that this is perhaps a rebuild ? Otherwise double checking bore length to string height, making sure the whippen cushions are the correct distance over the key bed, etc etc a good idea before going much further. Sounds like somethings a bit out of whack here. 44 mm blow is my minimum. Whats the key dip ? Pushing back check down further... just make sure you dont start pushing the wires through the key ends... been there done that :) Cheers RicB
