I have some fireblade carbs with Dynojet needle, they have grooves and a circlip to move the needle up and down to richen or weaken the mixture, they also have two 5mm washers that either go under the circlip or one below and one on top.
i keep getting conflicting answers does anybody know the correct position please ?
