The over revving situation had got the better of me so I decided to do the NormK carby modification minus the idle adjustment but I still have the problem although it starts perfectly.
What happens is that when I increase throttle position and the engine revs up, it gets to a certain point where it takes over and opens up the throttle fully and excessively by itself.
At the moment I have cut a thin piece of angle iron to the precise length and pop it in the slot the throttle slides in to stop it pulling itself open any further but I'm sure there is another way to fix this.
Any assistance appreciated, thanks
