Purchase (2) 140cc side discharge mowers late in 2012. The salesman sold me on the 'self priming' unit which at the time sounded like a good idea.
Used each for less than 3 hours each. Fast forward May, 2013: One mower will start only with starting fluid forced into the carb, the other won't start at all. No obstructions in the fuel lines, carb cleaner used (after 3 hours?!) Sears will not warranty since I did not purchase the extended warranty. I posted a scathing review on the Sears website that resulted in an email (to which I responded but have not heard anything).
Also, they won't post my review. What a horrible way to treat customers.
Review about: Sears Website.
Monetary Loss: $400.
