I had an issue with my Kohler Engine pull start assembly being locked up. AMP sent me to Kohler but it was going to take 3 weeks to replace. I informed AMP I needed the pressure washer I purchased. AMP sent me a brand new pressure washer and waited for Kohler themselves. Never expirenced a company willing to step up to the plate and correct an error that quick. I'll be purchasing from them from here on out!
