....forget the overpriced, overweight, and underpowered OS .61FX....they are dogs.

For the price of the OS, you can buy the S.T. 61, a S.T. .40, and a few gallons of fuel.

The ringed Super Tiger engines will still be running when the OS has been junked and
forgotten.....

....this from an "OS Man"....I have dozens of ringed OS engines.
