Rossi 90 help needed!
I have acquired two Rossi 90 engines. the first is currently in my Byron F-16 on a byrofan. The other I just bought. I am wonder what the differences are between the various rossi 90 engines. there is a 48 R 90, 58 R 90 and 98 R 90. The one I bought seems to be a 98 R 90. The carb is slightly different than the one in the F-16, but both are rear exhaust and rear carb. Can anyone help me out here?

The 58R90 is the engine for the Byron fan system with the large head. The 98R90 is the Dynamax/Ramtec version with the small head and remote needle. I don't know what the 48 is/was. Interestingly enough, the Byron version was rated at a higher RPM (28k vs 23k) and the tractor version had a higher hp. rating.
