Converting 2 stroke to clockwise rotation
IS it possible to modify an OS 25FX for clockwise rotation?

You will need a crankshaft that is machined with the intake port in a different location so that the intake timing is correct. On engines with a removable front plate like the K&B 3.5 or the O.S. .25VF you can rotate the front housing 90 degree and accomplish the same thing. Unfortunately, you can not rotate the front of your O.S. .25FX.

Having said that, is there an after-market crankshaft available?
