Carburetor leak

Dear All,

OK, I have rebuilt the Detroit Lubricator 51 carb on my 733 sedan (1930). Upon first use, there was a considerable amount of fuel that was freely flowing into the throat and out the air intake. I figured I had not tightened down the float valve seat sufficiently and fuel was running past it.

Took the thing apart, tightened the seat, and it 'seemed' cured. Only problem, it has started again, just slower. No extra fuel when the engine is running, but it definitely is there in the air intake upon letting the car sit overnight. Is there someplace else that I should check, or is it likely that I need to tighten that seat down even further? I really don't like wrenching on the carb, so I may still have been to delicate.

Any help will be much much appreciated.

Best regards,

Tom
