OMC 225 Carb Jets

Ok guys i guess this qusetion would go in the mod class, I want to modify my carb jets back to original size, so im going to fill em in with solder and drill em back out. I know i need 14s 28s and 62d's! Ok what drill sizes do i need for them sizes ? I thought they were the same as the sizes but they r not. Please help AGAIN.............Jeff
