Time for a yard sale or Craigs list!

Dads barn and buildings have a lot of good stuff, appearance wise. But they have been sitting for at least 6 years, he died last year at 87. A nice Cub mower, but the deck needs repair, 4 chain saws, 3 weed eaters, and 2 leaf blowers.

First task is to clean the carbs, all have old gas in them, and Dad was notorious for adding too much oil in the gas for the 2 strokes. He was also bad about adding to much oil in 4 strokes. I live next door and when I would start my old AC tractor it would smoke like crazy. I caught him one day, he couldn't see the fill line and was adding oil! LOL

Any suggestions on other stuff that I might need to do before trying to start them? I don't need to break my wrist again!
