Roller bearings will take untold abuse, as long as there is something slippery in the vicinity they are fine....stuff in the tappet screen is not a sign of Armageddon necessarily...the screen is there because bits do find their way around an Evo motor. I don't think its a bad as you think.
Tore the carb down... Cant see how it could have happened. Float needed some minor adjustment, but not to where it could cause that to happen. The needle was a little galled where the shim washers would go, so I cleaned that up. The needle is soft aluminum and the shims were steel, so I'm thinking that may have been the issue? I tested the petcock and it was working. Unhooked the fuel line and left the petcock on for an hour and got no fuel out of it. I'm stumped...
