Paul Jefferies Posted January 10, 2016 Share Posted January 10, 2016 There is one that looks the same currently on ebay. See Here It is described as an OPS 60 FRVSE....... I have a very similar rear exhaust OPS which dates from the early to mid 80s though the designation is quite different.......... Mine is an "SPA RCA" (whatever that may mean). However to borrow a saying, "Handsome is in the eye of the beholder" and I think they look GREAT!!!

Stevem3akm Posted January 10, 2016 Share Posted January 10, 2016 Hi, that is an OPS Ursus, good engine apart from the slide throttle carb. Better of replacing it with an OS unit. Regards Steve. Quote Link to comment Share on other sites More sharing options...

jeff2wings Posted January 11, 2016 Author Share Posted January 11, 2016 Thanks for the replies ,I don't think this is a Ursus (Bear) unless the name carried over to this model ,the Ursus first appeared around 1972 but this one is an '80's engine for sure ,it would be nice to know the prop/fuel/plug/pipe setup for this.
