QuestionQUESTION: I have a Toro 2 cycle that is 25 years old. It starts and runs fine for about 10 - 15 minutes then dies out. The engine seems to over rev.
Do I have a problem with the needle valve adjustment or is the Carb Float Saturated? Or is it just old and needs replacement?
ANSWER: Hello Greg:
Send me the Model Numbers Off the Unit, Please. With these I can Locate the Proper Manual and Better Assist you. The Following is a Basic Instruction File I made for this. Any Input is Appreciated. I Usually Suggest you Check the Following in this Order for a Problem like yours. 1- Check the Gas Tank Cap and Ensure it is Venting the Tank. A Vacuum Builds in the Tank and the Gas Flow Stops or Slows to a Point it Shuts Off the Engine. 2- Operate the Equipment Until it Quits (15 to 20min). Then Immediately Check for Fire from the Plug. If the Plug is Firing, then 3- Check the Carburetor Solenoid. If the Carburetor Shut Off Solenoid has Current, then Remove the Carburetor Solenoid and Go to the Hardware Store. Purchase a Bolt of the Same Diameter and Threads. It Needs to be 3/4" Long. 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 Jets. 4- Depending on the Model Mower, it can Also be the Pickup Tube in the Gas Tank. If No Fire, then Remove the Shut Off Wire from the Coil and Check for Fire. If Still No Fire, then the Ign Module or Coil is Bad. On JD Mowers; Remove the Igniter/Module and the Coil and have the Local JD Dealer Test them. 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
