Maybe I’ve been lucky but after many airheads and thousands of miles travelled I’ve never had a punctured diaphragm. The symptoms were, above 3000 revs on the road, not stationary, it felt as if it was running on to reserve. Very lumpy.
I weighed up the options and started with carbs first. I found the tiny holes , barely visible, by the securing plate. I had spares in stock. Problem sorted. Ironically the only bits I didn’t touch when I rebuilt the carbs as part of the winter restoration.
