Hello John:

Sorry for the Delay. This Question was Located in the Question Pool. Send me the Model Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. The Carburetor May have Picked Up Trash and the Carburetor Jets are Now Clogged. Is the Gas Up to the Fuel Pump and Carburetor Inlet? Sometimes the Fuel System has to be Primed. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.

Good Luck

Respectfully

John
