QuestionQUESTION: Hi. I have a riding mower that is at least 5-6 years old. It has worked great, overall. However, last fall it started up with a problem. When the mower is engaged, it has trouble with even small inclines. When this occurs, it slows down dramatically, often to a stop.
This used not to occur. In addition, it does fine on inclines without the mower engaged.
Would you advise me what this might be and/or where to start checking into this problem. I have experience doing most simple things on it, and I have a manual for it.
Thanks, Alan
ANSWER: Hello Alan:
If the Engine is Continuing to Run Proper, then the Ground Drive Belt is Worn. If the Engine is Slowly Losing RPMs, then the Carburetor May Require Cleaning. Send me the Model and Type or Spec Numbers Off the Engine and the Model Numbers Off the Mower, Please. With these I can Locate the Proper Manuals and Better Assist you. The Model Numbers May be Stamped Into the Blower Housing (metal engine cover) Above the Spark Plug. Thanks.

AnswerHello Again Alan:
Thanks for the Model Numbers. They Helped me A Lot. From your Description it Sounds like the Carburetor High Speed Jet is Restricted and the Carburetor Requires a Soaking and Cleaning. 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 (if Applicable), Float Pin (if Applicable), 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.** You can View a Breakdown/IPL of the Unit at this Site Addy; http://www.briggsandstratton.com/maint_repair/manual_and_more/doclist.aspx?categ and Enter the Model Numbers (28T707) and Type Numbers (1154) in the Appropriate Boxes and Click GO. Then Select Download PDF. The Carbuetor Needs to be Eleminated from the Possible Cause Before we can Continue to More Possible Causes. Usually the Problem you Described is Because of the Carburetor being Restricted with Varnish. You can View a Breakdown/IPL of this Unit at this Site Addy, http://www.smallenginepartswarehouse.com/parts.asp and Select the Shop Online Parts Look Up. Then Select the Model Tab. Then Select the OEM and Enter the Model Numbers. Then Double Click on the Model in the Results Area. Now you can Select the Section of the Unit you Wish to View.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
