Anybody have any tips or tricks on removing the brass idle and high speed feed tubes that go through the venturi? Im going to bore my carb out but haven't figured out the best way to remove them.

If possible try to acquire a 30hp carb same year as yours.

Ive got a 28hp carb which is essentially a 30hp but ive been a machinist for 10 years and its a mindset I have. Why spend $100 and 2 months searching when I can spend an hour by boring out my current carb, drilling out jets, and slap her on.
I gently worked on removing the tubes and they may be cast in so I decided it wasn't work messing with. i decided to just run my 28hp carb.

I read somewhere in a outboard repair book that those brass tubes
are indeed pressure fitted into the carb during manufacture.
I had the same idea - but I was hoping it was a threaded part to reverse it out.
It is a pressure fit at the factory from what I have read.
The only apparent way to get the tube out is to drill it out, just as you explained.
