I personally don't know anyone who runs alcohol.
But I do know, you need twice the jet than you need with gas.
How far to tell you to drill your jet, I know not. I feel I am
in the same catagory as most on this site. You are on the
right track, I won't give you a guess answer about how far to
take your jet.

When we race karts we use around a .048-.060 drilled jet for straight alky.  I know the stock gas jet is like .030.  Hope that helps.
