Glad you got a good result in the end. My old man used to hammer into us "Check the simple stuff first" when we were ready to strip a motorbike engine down to the crankpin because a loose tappet was rattling. He was right too, as usual!
You might put a dab of white paint or similar on that pulley, and the countershaft pulley, for future reference so you can see at a glance in the gloom if it is turning or not.
