You may find people saying “the bigger the better” while talking about the size of the carburetor. However, the size of your carburetor might depend on the repetitions you are looking for. Otherwise, if your carb is too big in proportionate to your engine, it might be a deterrent to the performance of your engine overall.
If you want about 5500-6000 rpm, you might need to use a 600-cfm carburetor. However, if you want a higher rate of about 6500 RPMs, you will need a 650-700 cfm carburetor.
As for performance, you will get a decent performance from a 600 cfm carburetor, but it is a good idea to get a carburetor of 700-750 cfm if you want to cover a multitude of functions.
