46mm webber questions

I bought some webber carbs that were supposed to be 46mm carbs. They are 40 IDT's and have had the bottom modified to enlarge them to 46mm. The work looks good but I have some questions.

1) Do real 46mm webbers share the housing with 40mm and are just bored out?

2) Do real 46mm webbers have different transition holes than 40mm? Mine has 4 holes instead of 3 and they are larger than on a set of 40's.

3) Do real 46mm webbers have different idle mixture screws? Mine stick out into the bores because the bases have been bored out.

4) Do I have any hope of making these run right?
