I was hoping someone could advise me with this.I have recently come
across a number of lawnboys with seized engines due to being run with
pure gas without oil mixed in.Some as new as 2003/04 models with the
dura-force engine.Now my issue is are they worth considering and what
would be most likely the extent of damage incurred? piston rings only?
can these seized pistons be released?how?etc.,etc.
Should I just stay away?
Also who manufactures the dura-force?was it lawnboy in-house?
sorry for all the questions

It's hard to say what damage is to be expected, but most likely you will have bad pistons, rings, cylinders, and possibly rod, rod bearings, and any moving parts inside the engine. I don't think I would consider them unless they were free or darn close. Then I'd probably check them out and fix what was easy to fix and take the others apart and sell the good parts on ebay.

The Dura-force is their own engine. Each will have to be torn down to assess the damage then check their website out for needed parts.
