Small Engines (Lawn Mowers, etc.): Craftsman gas blower/vacuum 32cc 2-cylce, blower vacuum, puff of smoke

Question
My leaf blower will start after priming and choking, idle for a few seconds, shut down, with a puff of smoke from muffler.  I have mixed new fuel, new plug (gapped properly), cleaned air filter, and no change.  I also have adjusted mix and idle per owners manual.  SOS!

Answer
 Hello Brad:

 Remove the Muffler and Check the Exhaust Port for Blockage. Check the Muffler and Spark Arrestor Screen(in the Muffler) for Blockage. Has the Fuel Filter been Changed? If the Muffler and Exhaust Port are Clear and the Filter has been changed, then it sounds like the Carburetor needs to be Cleaned and Rebuilt. Send me the Model Numbers Off of the Blower/Vacuum, Please. With these, I can Locate a Breakdown/IPL and Better Assist you. I am here if you Require more Assistance. let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully

 John
