Small Engines (Lawn Mowers, etc.): cub cadet dies while mowing, ac volts, cub cadet

Question
John
I have a model 2284 cub cadet with 450 hours on it. I put a new carb,plugs,fuel filter,ignition switch, pto switch and bypassed the saftey switch on the seat. Mower starts and runs fine but after mowing for a few minutes it dies like something is shutting the mower down and it will backfire through the exhaust. It will then start right back up and runs fine without a load on the motor. Any ideas? Thanks.

Hello Quint:

From your Description it Sounds like the Stator or Voltage Regulator is Not Charging Properly and Causing the Carburetor Solenoid to Shut Off the Engine Due to Low Voltage to the Solenoid. For Testing the Electrical (Charging) System on Mowers you can Use this Site Addy; http://faqs.custhelp.com/cgi-bin/faqs.cfg/php/enduser/std_adp.php?p_faqid=3438&p... and Use the Link for AC Volts/DC Amps Meter Setting Chart. This is for Briggs Engines and Works Well for Kohler and Other Engine OEMs. The Following is a Basic Instruction File I made for Checking the Carburetor Solenoid. Any Input is Appreciated. **Check for Current/Voltage (10.5 VDC Minimum) to the Carburetor Shut Off Solenoid. If the Carburetor Shut Off Solenoid has Current, then On Some Solenoids you can Remove the Needle and Replace the Solenoid to Test them. ****PLEASE DO NOT OPERATE THE MOWER WITH THE SOLENOID BYPASSED IN THIS MANNER. THIS IS "ONLY" FOR TESTING.**** For Others, Remove the Carburetor Solenoid and Go to the Hardware Store. Purchase a Bolt of the Same Diameter and Threads.It Needs to be 1/2" to 3/4" Long for the Horizontal Mount Solenoids and 1/4" Long for the Vertical Mount Solenoids. Put this Bolt in Place of the Solenoid. If this Corrects the Engine Problem, then Replace the Solenoid. ***NOTE: THIS IS FOR CHECKING THE SOLENOID ONLY I NEVER SUGGEST YOU OPERATE THE ENGINE WITH THE SOLENOID OUT OF THE CARBURETOR EXCEPT FOR TESTING PURPOSES*** Sometimes the Plunger is Moving, Just Not Far Enough to Allow the Gas to Enter the Jet.** You can View a Breakdown/IPL of this Unit at this Site Addy; http://www.jacobisalespartslookup.com/home.asp and Select the Cub Cadet Logo. Now Select Shop Online Parts Look Up. Now Select the OEM ( Cub Cadet) and Select the Model Tab. Then Enter the Model Numbers and Click Search. Then Double Click on your Model in the Results Area. Then Select Sectional View. Then 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
