My Coinola C2 Plays "Lights Out"

I recently worked on my Coinola C2 that I bought from the late Tim Trager collection just before his passing. I bought it "as is" with only the percussion playing. It was advertised on his website at the time. In the past few days, I went through every part of this machine and cleaned the tracker bar which had a monumental amount of dirt and dust in it. I didn't stop until I found the issue. I continued until I opened a pneumatic bellow by moving a metal knife to the opposite side of the cam in the stack cutoff and the C-2 ROARED to life!! Most recently, I removed the lock/cancel cover for the pipes and the pipes magically started playing! Maybe the cover prevented the pneumatic to open? The tune it is playing is "Lights Out"
