Thanks for the input. I thought it was just me.
I did find why the deck is so loud. The idler pulley bearing is dry or worn, and the spindle bearings are rough. The PO said they were the newer style tapered bearings, and he had worked on them. Something ain't right though. The center bearing locked up when I greased it. Dang, I was getting caught up on the mowing. I have the tech sheet that explains something about how the lower seal goes in so it can flush when it's greased. Maybe he put it in wrong. It'll be nice if I can get it up to snuff and make it a bit quieter.
That engine knock though has got me worried, but I suppose that's a gamble ya take with old stuff; even if the former owner claimed to have kept everything in shape himself.
