Small Engines (Lawn Mowers, etc.): Craftsman mower fuel starvation, fuel starvation, cleaning solution

Question
I own a two year old Craftsman 7.0 21" rear bag mower.  It's gotten to the point where after priming (red rubber pump primer on carb) it won't keep running.  I'll pump the primer 4 times, pull the crank, and it starts and runs but then dies.  I do this over and over, but it won't stay running.

Thanks!

Answer
 Hello Erv:

 Make Sure the Gas is Free Flowing to the Carburator Inlet. If it is, Then Remove the Carburator aand Clean and Rebuild it. Soak the Carburator in Cleaning Solution (Gunk carburator cleaner). Then Blow Out All the Passages with Compressed Air and Intall Kit. Send me the Make and Model Numbers Off of the Engine, Please. With these Numbewrs I May be Able to Locate a Breakdown for you to View Online. Hope this Helps. I am here if you Require more Asistance. Let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully
