I have been told i need a new diaphragm as my bike starts but cuts out due to petrol flow problems ..... could any one gimve me al ink to buy one please
a broken carb diaphragm usually doesnt cause this problem it will stop a bike from revving up as the diaphrams job is to inflate it when air is drawn into the back of the carb and that lifts the slide up its like aballoon filling with air and if it leaks it wont fill up.
