carburetor trouble

[HondaRaceReady]

Yeah, I've already searched and read all 4 past threads on this subject. My carburetor is leaking from the drain/overflow tube. I replaced the drain screw, float needle, and the float pin cause it was bent. I checked the float and it floats when put in gas and I dont see any gas inside them. I cleaned all dirt from between the float needle and float seat. After all this, it still leaks. The only thing I can think of is to replace the float seat. I can't find it on service honda and I can't even get the old one out. Do I need a new carburetor to fix this leak?

Chances are although the float seems ok it isnt. I had a similar problem on my 450r carb and replacing the float fixed it.

You did clean the float needle of course I assume?
