Yard Machine 24" that had a 10HP Tecumseh engine back in 1997 from Sams Club. The only thing I ever did to it was change the oil and replaced a valve stem that eventually split. Sold it after 16 years a few years ago and it was still in sound shape. A little bit of oil burning from the engine but nothing drastic, just enough to smell it when using. I bought an Ariens 24" Platinum to replace it, worst decision I made in a long time.
