I have no clue... whats your guess its probably as good as mine lol :poke::D ... I don't have a fuel pressure tester either. I have had thought about it being the fp too.

I should be close to 6psi when hot.
Its easy and cheap to do.
Without knowing the fuel pressure at the carb you are just wasting time and $
