Just to follow up, the problem was as originally diagnosed (diaphragms in
carbs) but BOTH were bad, not just one. I'm not sure how it ran at all
considering how torn up they were. I will now carry carb diaphragms in my
spares kit so if/when this happens again, I'll be ready. Thanks for all the
ideas/guesses/possibilities that you all offered.
