Hi there ive recently taken mi dellorto carb off mi yamaha aerox to clean it all up ive been told its not the right 1 to have on it because the jet size is smaller than what they would be on a normaly yamaha aerox carb. I cleaned my carb up and hav connected up all fuel pipes, airbox, automatic choke, throttle float but its not starting does any1 have any ideas why ive been told it might be too much air getting into the system i know theres compresion and a spark. thanks james!
