i have a 1976 2hp. i've had it since it was new and at the time i bought it it was just called a 2hp. i have been looking at used listing to try and figure a value for it. i have noticed that some are called a 2hp COLT. when did johnnyrude start calling them a Colt or was that a non USA designation? is there any differance? they look the same in the ad pictures.
