Quick thought. You say there is no feel of priming. Well mine is also 33 box and it probably takes 10 pumps where all you feel is the air you are sucking ahead of the fuel. There is no real feel of resistance. It is only after that when you feel the resistance and squirt of fuel coming through the pump to carb. I usually give it another 5 pumps after I hear and feel the first squirt.
It might therefore be that you simply aren't priming it enough rather than the diaphragm being damaged?
Oh and I fitted an electronic ignition in place of Bosch and it has made a difference, although perhaps not as much as if I had replaced a worn original.

Enjoy yourself, it's later than you think!
