Super Tiger .15

In my experience Super Tigres are among the best engines around. In my younger days they were way out of my price range when new, and hardly ever came up secondhand because people kept them! They were always considered contest engines, power and reliabilty were second to none.
How much are they worth? that depends on too many variables to give an answer, looking at the condition of the engine in the photo, it looks very good indeed. Whether you should buy it? Well, if you consider the asking price is reasonable, and you want the engine, buy it!
