Small Engines (Lawn Mowers, etc.): Craftsman Snow Blower 536.884810, gasoline smell, carburetor adjustment


Question
QUESTION: Hi John.  I see you answered a question about this model snow blower so I figured I would run one by you.

This is a track drive unit (no wheels) but it is exceptionally difficult to move when the unit is not running and in gear.  I can barely move it around in my garage. Is there a way to disengage the drive system so that it can be maneuvered when not running?

Thanks
John

ANSWER: Hello John:

I have 2 Regular Customers that have the Same Snow Thrower. They Love the Unit, but have the Same Complaint you have. It is Near Impossible to Move this Unit when it is Not Running. I have Looked these Units Over and found that the Drive System is Disengaging, but there are Chains and Gears that the Operator is Moving when they Try to Move the Unit Manually. These Chains and Gears Can Not be Disengaged and Cause the Hard to "Hard to Move" Problem when the Unit is Not Running. I have to Send the Pick Up Vehicle with a Dolly (low Profile) and Use the Dolly to Load the Unit if the Engine is Not Starting. I Used to Use a Winch to Load them, but the Dolly Works Better. Rolling Wheels are Easier than Rolling Tracks. Sorry I was Not of More Assistance. 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. Have a Happy Holiday Season and May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.

Good Luck

QUESTION: Thanks.  Another question.  The engine starts well and runs pretty well too except for some sputtering.  I notice a strong gasoline smell after it has been running and it's back in the garage.  The whole garage smells of gas for about a day.  I suspect a carburetor adjustment may correct the sputtering and gas smell but I am not sure what to do.  There are no leaks that I see.  I have no manual.  I think the engine is a Tecumseh but I am not sure and don't know the engine model number to google it and find a manual.  Do you by chance know this?

Any advice would be appreciated.
John

ANSWER: Hello Again John:

If the Engine is the Original Engine, then the Engine Model Number is 143.794053 and it is a Tecumseh. 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. 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 Might want to Check the Crankcase Oil for Gas Contamination also. If the Carburetor Float Needle is the Cause of this Problem, then the Crankcase Oil will Most Likely be Contaminated. Install a Manual Cut Off Valve in the Gas Line and Turn Off the Gas Flow when the Unit is Not in Use. 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. Have a Happy Holiday Season and May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.

Good Luck

QUESTION: Hi John,
I'm close to getting this snowblower fully functional but I have another question.  I bought a carb kit, installed the new seals and needle valves, and a new spark plug.  It seems to run real well now.  But I have a leak from the carb.  I found a very small pin hole just below the top flange of the carb body about 1/4 inch to the right and 3/4 inch above the idle adjustment screw.  It's so small but it seems to be a perfect circle like it's supposed to be there.  But when the engine runs fuel leaks through it at a pretty good rate (steady drips).  I am inclined to just put a small dab of some sort of sealant over the hole and be done with it.  But I don't want to cover over a hole that may be there on purpose.  Are you familiar with this?  Thanks again for your excellent help.

Answer
Hi John:

I am Glad to Hear the Unit is Running Better. Did you Check the Carburetor Float and Make Sure it was Level when Installed and the Carburetor is Turned so the Float is Facing Up. It Sounds like the Carburetor is Flooding Slightly and the Excess Gas is Leaking Through the Bowl Vent. Check the Float and Make Sure the Float Needle Valve is Seating Correctly. The Float Needle Valve Kits that are Produced Today are Sometimes Bad and Allows for this Problem Also. 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.
