Diaphragm Carburetter

For starters I have NO knowedge as to the workings of a diaphragm carburetter.
I have a tecumseh with a diaphragm carburetter( with a primer bulb ). The problem is that when I shut down the engine gas starts to run out of the carburette. Without a float, I'm lost!

Hello: Gordo

The diaphragm simply flutters up and down and in doing so lifts and lowers the fuel needle. Fuel passes when the needle is lifted off the needles seat, almost like a float carbs.

The most likely problems are, based soley upon the problem description, is the needle isn't fully closing, the diaphragm and or needles seat is damaged and or the carbs adjustment screws are incorrectly adjusted.

Most likely I have not covered all of the potential possibilities. The other resident small engine service and repair professionals may offer additional suggestions, advice & help.
