How do I remove a stuck in float seat from an NH carb?
I heat them red hot with a torch and then let them cool completely. After it is completely cool put penetrating oil on it and it should come right out.
Don't try to turn it while it is hot!!!!!!!!!!!
Heat.

Someone needs to make a tool to fit that seat, that has a pilot in it, and slots that fit tightly into the seat. I think they would sell.
Jack Daron makes them.
Thanks for the advice guys. I heated the body with my little MAP soldering torch and quenched it ice water. Both seats screwed right out! The carb is back together, not leaking anymore and is working fine on my buddies T! I used a new float seat and viton tipped needle.
You can whittle out a "seat tool" out of cheap old wood chisels. Bottom center in this picture.
