Oh well, There was a fellow who had lots of old parts on RCU years ago...got a case for an OS 60 FS (PRIOR TO SURPASS) for a fair price. Just though it was worth the effort.
Thanks,
Bruce
The two-stroke OS engines have the letters after the displacement size, such as OS .61AX. The four-stroke OS engines have the letters before the displacement size, such as OS FS-91, now out of production, I believe.
