Like a lot of twins Dukes had the same trouble that a lot of twin manufacturers had,namely feeding both cylinders equal volume. Also he had a few parts that needed adjustment so most including mine went back for a visit at the factory. As a glow it was mediocre. Did I mention that it wasn't the best on fuel economy either. I converted it to ignition with Bill Carpenters aka CHS electronics twin system and installed HB40 carbs on and it was a reliable runner. To reduce the extra needed ignition accessories I converted again to diesel with Davis heads. This gave me the advantage of being to adjust the timing and fuel mixture to each cylinder individually.It then ran about the best that it was ever going to do. It ran well enough that a diehard Fox lover had to have it for a project and I sold it off to him.
Do I miss it and wish that I had it back, not really. There were so many other better designed engines that were less problimatical that I never looked back with any warm feelings about the critter.
