Improving acceleration using 2bbl Carburetor?

I'm working on getting to doing all of my own work. This is my first car and the first car I've worked on. I saw it being abused and neglected by a kid at my high school and so I bought it off of him and I figure I'll use it to learn all I can. My mechanic has done very good work generally, but this has been my one gripe

He may well not be familiar with carburetors. That's fairly common nowadays.
