Default RE: Info on an old OS 90 engine

ORIGINAL: kerrydel

A guy at the club gave me this engine. I can't seem to find any info on it even from the O.S. web site. It's like they never made it.

What I'm really interested in is finding a pitts muffler for it. The spacing of the muffler mounting bolts is 53 mm (2 1/16").

Any info is greatly appreciated.

Kerry

I have one of these engines as well as the .91 FX. What Dar says is true. The Older FSR is heavier and but produces more power and IMO throttles better.

This is the Pitts Muffler you are looking for. The 1.08 shares the same exhaust.

Regards,
Jeff
