Question about 1978 Yamaha RD 250
Doesnt seem to be running right 1 minute ok next stugling then carb floods checked floats ok running rich on oil what are the point setings where can i get fre down load info on this model
Check the neddle valve seats under the float bowls,may find that theseats are not sealing,to test,take the carbs off the bike,remove the bowls ,compress the floats untill they are all the way up(simulates full bowl of fuel)then blow through the fuel inlet pipe,you should not be able to hear air passing throgh the valve if you can replace the valve seat and the needle valve,sorry cant remember point settings,long time ago since i worked on one of these
