Small Engines (Lawn Mowers, etc.): snowblower shuts down, spec numbers, valve clearances


Question
QUESTION: I have a Craftsman 11 horsepower snowblower maybe 9 years old. Just used it 2 weeks ago and was a beast. Today, in preparation for a storm I started it. It ran rough then stopped. Did this over and over. Changed the plug, and sprayed engine starter in the carb. Started up and ran for 2 minutes then stopped again. While this started the exhaust got extremely hot, even glowed a tad of red. When I push on the primer I hear air squirting out and not gas. Is that normal and what should I do to get this thing going for me. My driveway is 200 feet long and will be trapped without it. Any quick tips would be helpful.

Thanks,
Barry in Avon ma.

ANSWER: Hello Barry:

If this is an OHV Engine, then the Valve Clearances May Require Resetting. The Carburetor May Require Cleaning. Send me the Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck

QUESTION: Thanks John. It is a Craftsman 11.0 Horsepower 30 inch dual stage Snow Thrower Model # 536.881130. It ran great 2 weeks ago and then this happened. I did all the routine adjusting. Oil Spark Plug, changed gas, etc etc. But I push on the primer it seems like only air is going through. Then it would run and the exhaust would begin to glow slightly, back fire and shut down. Thanks for you quick response. I will certainly use you again when needed. as a home owner I'm always involved in some sort of project.
Many Thanks,
Barry

Answer
Hello Again Barry:

Thanks for the Numbers. From the Breakdown I See this is Not an OHV Engine. I Suggest you  Remove, Disassemble and Soak the Carburetor Overnight in Carburetor Cleaner (I Use Gunk). I have Found that Most People can Use a Breakdown/IPL and Disassemble the Carburetor Enough for Proper Cleaning. You Only have to Remove the Bowl, Float Pin, Float (if Applicable)  and Needle Valve and Any Adjustment Screws that Go Into the Carburetor Body. The Welch Plugs Do Not have to be Removed. Then Soak the Carburetor Body and Parts in a 1 Gallon Can of Gunk Carburetor Cleaner Overnight. The Can has a Parts Tray Inside it for the Small Parts. Once the Carburetor and Parts are in the Cleaner, you can Replace the Lid for Safety and to Prevent Accidental Spillage. Then Blow Out the Passages with Compressed Air. Install New Parts if Required. Since this is a Tecumseh Engine, I have a PDF Site Addy that May Assist you Also. http://www.tecumsehpower.com/CustomerService/BSI.pdf. You can View a Breakdown/IPL of this Engine at this Site Addy, http://www.outdoordistributors.com/ and Select the T. Then Select Tecumseh. Then Select Don't have Part Numbers. Then Enter the Model Numbers. Then Select your Model and Download the File for Online Viewing. If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck
