You need to adjust carb on the side of carb there is a mixture adjustment screw on slow slowly turn screw out until surging stops now go full throttle if die need rebuild carb if runs fine your done

Do you have to plug the battery in in order to recharge it?
SOURCE: Engine revs wide open when starting
Check to see if the throttle shaft on the carburetor is actually moving (with engine off) Does it slow down when you move the throttle control on the dash?
Start it up and try moving the linkage on the governor shaft, if there is little or no resistance but the engine slows when you move it, most likely you have a broken governor gear inside the engine. Another possibility is that the screws that hold the throttle plate to the shaft have come loose and the plate is jammed in the throat of the carburetor

SOUNDS LIKE IT HAS SOME BAD GAS YOU MAY NEED TO CLEAN THE CARB AND IT MAY NEED A KIT

Hi and welcome to FixYa, I am Kelly. I understand you have a 10 HP Tecumseh engine. There are service manuals available on line for your engine but without your engine model number it is difficult to pass you the correct one: Here is the link for the service manuals:
http://www.mymowerparts.com/pdf/Tecumseh_Service_and_Repair_Manuals
Somewhere in the list is your manual.
This is my best guess without your engine model number:

^-Make sure you read about Adjustments in section 1 also.
Running wide open causes:
1. Broken throttle control plate spring
2. Governor spring problem
3. Internal Governor flyweight has departed the governor gear.
4. Throttle plate (butterfly) attached to the throttle shaft in the carb throat has come off the throttle shaft.
5. Broken / missing linkage
6. Someone loosened the governor shaft bolt at the base of the governor arm and allowed the governor to get out of adjstment.
Thanks for choosing FixYa,
Kelly
