So I was looking at some carbs yesterday and noticed a difference in the venturi. The exit or head side has a different angle and the i.d. is smaller than the other. So this got me thinking. Which one flows better? What would the smaller i.d. carb do to overall engine performance? Well after some testing. The larger i.d. carb has advantages. It can handle a larger idle jet. And it had around 200 more rpm. The smaller I.d. seemed to get lazy towards the higher rpm ranges (takes longer to gain rpm).
I'm I making any sense here?
P.S. : Whats the AKRA rule on machining the carbs?
