people suggested it was ignition, others i spoke to suggested fuelling, so i have done the following-
New dizzy cap, rotor arm, plug leads, (at the cost of £45!!!!!! ) replaced the fuel line between the pump, vapour chamber and carb as i noticed they were starting to split, took the top off the carb and gave it the cleaning of its life (inluding the gauze filter)
and guess what...... it's still bloody doing it !!!!!!
juddering, power cutting out when revved over 4000, but running fine at all other times, and it will happily run to the red line in neutral
what could this be????
fuel pump?, ignition timing? totally ****ed engine?
