I've got an older power tow model 35 for sale. I believe it's setup for a 182. It starts right up and runs smooth. I just replaced the fuel line and carb bowl gasket. You'll need to pick it up at KLOM (near Philly). It's not pretty but it works fine.

These are great tugs and $300 is a steal. Use as-is or put a small amount of work into it and have a ~ $1K tug.

This powertow is sold.
