Small Engines (Lawn Mowers, etc.): Non starting lawn mower, murray lawnmower, carbuerator

Question
John -

Thanks for the info.  I soaked the carbuerator in carb cleaner for 24 hours, and reassembled the mower.  Unfortunately, no dice.  The mower still revs up after priming, but doesn't pull any fuel other than what it gets from the prime.

The info you requested is as follows:
Engine Type:  B&S Quatro 4.0
Model #:  204210X99A
Serial #:  7460105111AQ182

I appreciate any advice you might have.  Unfortunately, my lawn is now quite long and my lawn mower continues to sit in the garage... mocking me.  

Thanks for the help!

I have a Murray lawnmower with a B&S 4.0 Quatro engine.  It's only 5 years old and I've never had engine problems until two days ago.  We recently moved and the movers drained the engine of gas.  I refilled the tank and tried to start it, but to no avail.  The engine would run on the fuel it got from the prime but would then stop.  It seemed that the engine wouldn't pull any fuel aside from what it gets off the prime.

I took apart the entire carbuerator, and cleaned it with B&S carb choke cleaner.  I also drained the fuel tank and cleaned it with the cleaner.  I ensured the fuel filters were also free from any clogs.  Finally, just to be sure, I also changed the oil, and replaced the spark plug and oil foam element (air filter).  Still, the engine won't pull any fuel apart from the small amount it gets from when the prime.  

I'm at a loss as to what to do now.

 Hello Lance:

 The Carburator needs to be Soaked Overnight in Cleaning Solution. The Gas Forms a Varnish Over Time and this Restricts the Gas Flow to the Jets. Using a Carburator Cleaner out of a Spray Can has Never Worked to Properly Clean a Carburator of this Varnish. After the Carburator has Soaked, Blow All the Ports and Passages Out with Compressed Air. This should Solve the Problem. If you Require more Assistance, Send me the Model, Type and Code Numbers Off of the Engine, Please. With these Numbers I can View a Breakdown of the Engine and Better Assist you. Hope this Helps. Let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully

 John

 Hello Lance:

 If you Soaked the Carburator and Used Compressed Air to Blow out All the Passages of the Carburator, then Replacing the Carburator is your Only Choice Left. It doesnt Happens Very Often, but Occasionally this Happens. Hope this Helps. Let me know what Happens, Please. Thanks.

 Good Luck
