I bought this Carter AFB from a fellow hamb member. It looked clean from the outside, but after installing it seemed to be clogged. Fuel was not coming out of the jets but the fuel bowls were full. So I took it apart and found some corrosion on the inside, mainly in one fuel bowl. I cleaned it pretty thoroughly with carb cleaner and compressed air. Do you think with that amount of corrosion that it should have a full rebuild?
