    Excellent service. First off he worked with me on the price. Secondly, he took the time to reach out to me and tell me a little more about the carb before shipping. He completely took it apart and cleaned it to be sure that it would be in perfect working condition when I got it. It was packaged to withstand whatever the shipping companies could put it through. I definitely would purchase from him again.
