Just make sure the carb bodies are spotlessly clean and put everything back together with the new o-rings. If you do the job right, and check everything as you go, carb problems will be a thing of your past.

A few key things to check are the float needle and seat and the float height. The float needle should not have any wear on it where it mates to the seat - nice smooth surface on the pointy area of the needle. Set the float height to spec, I set mine to the low end of the spec because this will result in a slightly richer running carb.

You can check the function of the float needle and seat by putting a small piece of tubing on the carb fuel inlet port and blowing into it - lift the carb float and the air flow should stop completely (carb needs to be in the upright position).

Assuming you verify the float functions properly, overfilling of the carbs, and leaking fuel, should be a thing of the past.
