Originally posted by Buck1400 I am restoring a 1973 Yamaha RD 250 and need help with the hoses that come off the carburator. I know the ones that recieve the fuel from the tank and the one hose that connects the carburator together (on the inside on each carburator facing each other). But on each carburator there is a port about mid way of the throttle body and another from the bowl at the bottom, i don't know where they go....HELP PLEASE. Once i figure this out i can start it!!!!
