Hello Mike . I have to agree , workmanship is top notch !I tried one of Frank's new .350 carbs and the boat launched better and had more top end than any other carb I have tried. Workmanship is second to none. He has done a lot of testing to get it to where it is today. You have to look closely to see some of things that make it perform. Too bad Frank doesn't have a production line. He sells them as fast as he can make them. Keep up the good work Frank.
