Ryobi model 725r, gas powered. Got it a couple of years ago at the dump free store (don't we all miss that!) from the guy who was there to drop it off. He said it was working fine. I put it away for a year or two and then couldn't start it. Maybe old gas, needs a tune up, or who knows what. I ended up getting a Ryobi battery model. If you like to tinker, here you go.
