Yep. A common issue with these decks. I have run into it many times. I have photos on here showing what the culprit is. Its the metal sliding bars at the bottom of the deck. The red circles show the pins that prevent the keys from working when the slide bar is in the wrong position. Those opposing springs at the bottom right of the picture are supposed to center the slide bar. That gold colored slide bar is supposed to move freely back and forth. If it sticks, you are going to have problems. Also the green circle shows the position of the solenoid shut off lever. When put together, if this isn't lined up correctly it will cause binding.
