Hi Paul,
It will be obvious if you've opened up the bypass holes sufficiently. You will see a clean hole which is larger than its neighbour. If the bit hasn't gone through all the way, you'll sort of have a smeared opening where the bit has not completed the cut. To check, take the drill bit in your fingers and offer it to the hole. It will slide in and out a few mil which will again be obvious to tell.
Remove/fit the throttle cables with the carbs out to the side of the engine, not while they're in place in the stubs. You can balance the bank of carbs on your left knee while guiding the cables in to place. Takes me about a minute to do both using that method.
