I can't imagine why Rolls concluded that wouldn't be a success.
RR now also own Continental, which explains a Cessna 150 I saw the other day with R/R decals on the engine hood!
Er, no they don't. The Chinese have owned Continental for several years:

I suspect you are thinking of the arrangement that Rolls-Royce had with Continental to licence-build some of their engine models in the 1960s/70s to power Reims-built Cessnas, including no doubt the one that you saw.
