Been trying to chase down a hiss, which I figured was a vacuum leak. It was coming from somewhere around the blower which I thought was odd but whatever. Went around everything including the manifold with carb cleaner to see if I could nail it down and nothing.
Gave it a bit of rpm to see if the hiss increased or not and it didn't. So was checking we'll more or less everything in that area. Found the belt slipped a rib on the jackshaft pulley and loosened off the tensioner to adjust it - which is when I found this play on the blower pulley that I'm pretty sure isn't supposed to be there lol (but feel free to correct me if I'm wrong). There doesn't seem to be any beRing noise out of the norm, they are noisy anyways. It still spins pretty smooth but sure seems like it isn't engaging with the impeller to do make the world go round. So not sure if this indicates a shaft problem or what. It doesn't seem to catch, grind or anything else regardless if it is pushed in or pulled out. Surely this can't be normal right? Wanted to float this past you guys before I pull it all apart for inspection.
