RE: Strombecker
Yes I do remember the SU. I think my kids Bug Eyed Sprite had them. I don't remember what my 70 Spitfire has, but it may also. Raining here, and I am not about to take off the cover to find out. As I recall the SU had oil dapening on the carb piston, and if you ran it dry, it did funny things.
