hi i recently purchased a nc23 aero model with a carburettor problem, the problem is the bike takes a lot of time to start, if it does start , it doesnt rev up, and it soon gets stuck till 3000 rpm and then just dies.
i know its a carburettor problem as the vehicle works fine with a Superfour carburettor. any suggestions would be welcome

Morning...

It sounds to me that they want a bloody good clean as your pilot system sounds blocked.

Strip them and drop them in the ultrasonic bath. If you don't have one a good scrub using petrol and a tin of carb cleanse should do the trick

thanks. i shall try that today. hope it works. but is there any other alternative?
