I have a 7KW generator that makes a hell of a racket on a cold frozen

on an air cooled engine, if so what type or suggestions on how to
quiet this thing.

Thanks

What you may want to try is building an enclosure that will house the
generator. The enclosure would be insulated, to dampen the noise.

The enclosure would have to be large enough to have at least a few inches of
room all around the generator. You'd also want to leave open one side of the
enclosure so that the exhaust had a place to go and also to prevent a fire.
You could then staple either insulation on the walls and cieling of the
enclosure or find egg-shell type sound proofing material to use. It will
not dampen the sound totally but could help.
