There’s no denying that if your blades are still open passed the transfer slots that you need more idle air to at least get the blades centered over the slots..
I have a larger number drill set and when I need to this I drill the throttle blades.
I start off with a number 53 bit which is about .060”.
If my blades are above the slots I drill two holes in each blade right off the bat.
Most times 3 holes drilled gets the job very well in the ball park, if not then I drill 4.
The nice thing about drilling the blades is if you go too far it’s easy to fill them in.
Since I don’t know what cam you are running if you want to be on the really safe side start off with one number # 60 hole in each blade, this is .040”.
This all assumes that you have at least 8 degrees of base timing in the motor .
