Not to me. If you had a huge amount of air slamming into the carby,
or at least more huge than usual, then you should have been making
hugely more power.
I've changed one diaphragm so far and the replacement is still
working ok.
Some fail and some don't although I suspect that more than a couple of
backfires through the carby won't do the longevity any good.

Yeah, not cheap in any currency.
