Ive drilled out my fuel bowl to main stack to the recommended 2.5mm to help prevent fuel starvation.
The problem is Im not sure if ive drilled through far enough? I cant see the drill when I look down the main stack hole? When i measure how far I drilled through its around 10mm. But when I make a close up photo of the drilled hole I still see a small edge at the back of where I have drilled. Is this expected or do I need to drill more? Just dont want to drill right through. Here is a photo. Cheers Robbie

A hand drill set is most useful here - you won't break through the bottom because you will feel the bit when you reach the stack turning free.
Called a pin vise.
