A large piece of plate glass is perfectly flat, or near enough, and gluing a piece of sandpaper to it and moving the part in a figure 8 pattern over it will bring the surface flat. This works great, also on other parts like accelerator pump covers and power valve flanges, or thermostat housings.
Sometimes you'll hear people say never use a torque wrench on carburetor flange nuts.
That's probably good advice for the careless sort who can't be bothered with torqueing the fasteners in a criss-cross pattern in small increments, but loose flange nuts are very common and will result in subtle air leaks that are difficult to detect.

I usually start with a large ******* file to determine how bad everything is. Then a double cut file to get it close the back to the ******* until is in the ballpark. I have a sink cutout 1.25" thick marble put some oil on it that will hold a sheet of 400 w/d and more oil and get with sanding then finish it off with 600.
