There is an 8.5 fitted to the Yardbug and my Yardbug has a 5.5 with the @#$+� 22mm output shaft not stepped. Maybe overseas they ran the 25mm output shaft and thats the pulley i need.
If someone can tell me if the Rover colt 5 and 8 motors are physically the same size and if they are need the 8. Strip the crank out of the 8 and get the shaft machined down to 22mm and my problem is solved.
