I took a couple of 2 barrell carbs apart. Maybe 3 but don't remember. Decided to break them down before scrapping them. I have 2 bases.........I was a carter and 1 was a Rochester from what I remember. Anyway I have all of the screws and internals for the most part in the box pictured. Good for spare parts..........and misc screws. I'll give it through this weekend if no interest them scrap it is. $10 + shipping from 60586. Thanks, Brian
