'Re-gassed'? as in getting the mini damper re charged or something? I'm not sure I know what you meant, Oz. Oh BTW, since your 'down under'....is your Cub a R\H drive?....*lol
Update: I checked my parts manual and didn't see the 'torsion' spring for drive that you were referring to. If it's not too much trouble OZ, could you list the p\n so I can locate it?
Thanks in advance,
Mike
