Hello nan11580, Great to hear from you. Yes there is a adjustment. There is most likely (not sure of the movement you have) A cam on one of the strike train wheels that lifts a lever which in turn moves the paddle that is attached to the rod that the bird sits on....o.k. now I am confused
....if that cam is set up to far along and starting to lift that lever it can start to move everything that pushes the bird out...just enough to open the door a smidgen when it goes into warning....hope that makes sense....the adjustment can be made by changing the gathering pallet position though you must make certain the strike locking pin is captured by the locking lever when everything is set, may also throw off the bellow and hammer lifting wheel so that too may need adjustment. Just so you know, repair or adjustment questions can be put up on the general forum..they are much easier for us to see when a new post is up. Have fun. William
