I cant say for Newell but most air governors have 2 through bolts with a nut on the other side. I usually snap them off with a 1/2 inch impact and replace with new ones. Newell quite possibly welded the nuts though. Hard to say. They get really corroded from the difference in metals and road grime. Otherwise let penetrating oil sit for a few hours then spray it again and try a wiggle. If i recall correctly they should be 1/4 20 by 2 and a half with a nyloc nut.
