Is the Cham[ion 400 supposed to be a mulyi-directional crank blower? I picked one up the other day on a trade, and it was seized, and nothing'd come off. Today I got all the oil ports off, and had to drill-out one of the bolts on the top gear box cover, (yes I know penetrating oil didn't work) I even tried a hammer impact with a flat blade end. (Sheared the vintage Snap On blade off). Upon closer inspection of the internals. ITS MINT (all but the gear box cover bolt)!!! Stands perfect, but its difficult to turn one way, and it won't turn at all the other way. I'm thinking it may have something to do with the worm-drive shaft being loose. Because when I look down into the blower and turn the crank, it appears to slip 1/16th forward.
