hi, hope someone can help. i have a cb500t 1975. i have replaced the entire electrics. and have a newtronic ignition. i have ridden the bike fine, but then one day went to start it and i have always had problems starting the %!¤, but now there is now power. it will run just about on tick over, i have tightened the idle screws in and it changes nothing. you can rev and it will pick up then die out, if you just leave it then it will also fade out. i have just stripped the carbs, and they seem all clear. i just don´t know what to do. i have got new coils, but I´m not sure they are great, there isn´t much of a fat spark. thats what i hoped from the newtronics system. any pointers?
