I have a Ryobi pressure washer that is not working. I called and was informed they would work on the pressure washer. I drove 40 minutes, one way, to drop off the item. Upon arrival I was then informed they do not work on Ryobi gas engines. I was furious and said I just drove 40 minutes and they guy looked at me as said "oh well". What a joke. I will never go back there. They could have cared less they just wasted 80 minutes of my time.
