Walk Behind Lawn Mowers

Hi,
Do you have a product recall list? While searching for a repair shop for my "BlackMax" mower purchased at Sam's Club last year, I've noticed that there are a lot of people with the same problem. The mower worked fine for a couple of months, then stopped. From most of the responses, there seems to be a design issue with the valves getting stuck in place, preventing gas from starting the engine.

Thanks!
