Check the prop. If it has the correct prop for a C-90, and it is pulling the correct RPM at full throttle, it's a good indication that it's a c-90. I was told that my Coupe had an 85, but I couldn't substanciate it by the logs. It did have the correct prop for the 85, and it pulled the correct rpm. I later tore into the carb, and sure nuff, it was jetted correctly for the 85. If it looks like a skunk, and it smells like a skunk, most likely it is one.
