P&H Welder WNT80

[The no name sasquatch]

I recently came across a P&H WNT80 Welder paired to a Wisconsin TF engine. The lady is wanting $450 for it and was curious on how much these welders/engines go for. When I went and looked at the welder I could not get the engine to turn over by hand assuming it’s cause the exhaust was not covered all the way and it’s been sitting out in the weather for 2 months according to her. The spark plugs did have a little rust on them so I figured the engine was froze she did say it turned over 2 months ago but her son fell ill and it’s sat since then. There’s not much on WNT80’s on the web so figured I’d ask here. I will post some pictures below.
