Default 3x2 carb problems

Why do my carbs keep loading up after I shut the car down and leave it sit for a week or so. They are dumping gas when I start it and I have to readjust all the floats and idle mixture in the center. What size jets should the have in them???

Center carb uses #64 jets, end carbs use metering plates equivalent to .076".

It's difficult to answer your question about why the carburetors are leaking fuel into the engine. The surfaces could be warped and leaking internally, the fuel could be boiling, the air bleeds could be clogged etc.

Make sure the float is set just below the sight hole, and if the engine has a heat riser wire it open.
