Started up the Gen & heard a different sound. The pully on the blower was wabling. Took it off & the set screw had backed out & worn out the hub +/-.15. The root cause was the hub had been machined (narrowed) & about 20% of the set screw threads were exposed.
I'm thinking this could not be factory made, but?
Grainger had a replacement 6.25" vs 6" original OD P# 5RJE4 for $38.25.
The new hub is much thicker, but I was able to put the set screw on the outside vs inside on the original? & it works fine.
Word to the wise...............Check your set screw tightness!!!!!!!!!!!!!!!!
