If you had water in the tank you probably had it in the carburetor too.
Carbs are made out of really cheap metal that turns into insoluble white
salt on contact with water. I am thinking that you need to get a carburetor
kit and completely disassemble and clean everything. If you do that, then
you at least eliminate the carburetor as a source of the problem.

When you had the tank out, how exactly did you get the water out of it? I
like to leave them in the hot sun for a day or two, so it is really "dry as
a bone" in there. This time of year, that may not be so practical, but the
inside of that tank has to be dry.

With water in the tank, it could also be in the canister and other parts of
the fuel system.

Carbs are made out of really cheap metal that turns into insoluble white
salt on contact with water. I am thinking that you need to get a carburetor
kit and completely disassemble and clean everything. If you do that, then
you at least eliminate the carburetor as a source of the problem.

When you had the tank out, how exactly did you get the water out of it? I
like to leave them in the hot sun for a day or two, so it is really "dry as
