Zenith carb float level

[Burgamot]

I have tried to stop my carb from dripping when shut off. I have gone through the card, still leaks. Today put in new valve seat from Snyder’s. I noticed it was different from what was in there and that it only came with one washer. When I put the valve in the float was only 1/2 inch above the body. I had to add a washer to get it 5/8 inch and it still leaks. My question is do I add or remove washers under the valve seat to lower the level of fuel in the bowl?
