Small Engines (Lawn Mowers, etc.): Carbureator flooding, rear tine, piece of dirt

Question
I have a 8hp rear tine rototiller.  I have been overseas the past 4 years and it has been in storage.  No problem with it starting up BUT.. I noticed copious amounts of fuel leaking from air filter.  I removed the filter and there is a steady stream of gasoline flowing while unit is not running.  Naturally with it running it gets too rich and cuts off and the fuel continues to flow.  I have only shifted the choke in attempts to stymie flow. Pan under carburator now as I type this.  Easy solution I am sure.  Please point me in right direction.  Thanks.. Mike

Answer
Hi Mike,

It sounds to me like the carb's float is not closing.  There may be a piece of dirt or gummed fuel inside.  I would remove the float bowl and take a look.  A new needle and seat may be needed.  Inspect the float itself, also.

Let me know how you make out.
