So I have a 1978 cb 400t with a dual carb with an accelerator pump set up. I found a cb 400a part bike which I took the carbs off the bike. I have to rebuild my carb bc its currently leaking on the seals of the carbs. I was going to rebuild the cb 400a carbs since they are both the same but the a doesnt use an accelerator pump on the carb so I was wondering I know what the pump does but which one is more efficient and without the accel pump how bad would the bike accelerate?
