RE: O.S. Engines now made in China
How can you determine fit at the LHS? Did they let you take them apart? If you are just flipping the prop a Magnum will seem to have the same fit. But they are worlds apart. OS has good quality control over their fit, much better than Magnum. It's just a shameOS fit is soo loose. If they were tighter from the factory they would last longer.
