On my BJ8 I have never used lockwashers on the carb mounting nuts, because the carbs don't need them, those nuts never come loose. I note that I've seen BN1s with H4 carbs using lockwashers on the big two nuts - do I need to be using lockwashers on these nuts? I'd prefer not to. Any advise? Alan '52 A90 '53 BN1 '64 BJ8
