Help on Clone motor

[ExtremeRacing]

At our track we can change lil things like the header and the air filter on our clone motor. But if u put a bigger air filter on it then it get to much air not enough Fuel. Been told to drill out the carb but no one said what size to drill it out. Can someone help me with this info please. I know if u do it right it goes from a 6.5 hp to around 8 just by doin that
