adjust the idle speed screw.
Lack of fuel.
you need to adjust the idle speed screw on the carb
In addition, check spark. Check electrical connections. Check fuel for contamination and flow. (The tool is called "a glass jar," dude.) Clean carburetor. (The tool is called "carb cleaner," dude.) I would check the maintenance history and the shop manual... but that's me wanting to know what I'm doin'.
It could have formed a vacuum in the fuel line by the tank NOT being vented or the vent clogged, loosen the gas cap and see if it will stay running then, if so, you know what your problem is....get a new gas cap.
If that doesnt fix it, then your carb needs cleaning. AND or the float in the carb. needs to be adjusted and the needle valve cleaned.
Does it run with partial choke? Try a new spark plug....you'll be amazed.
Set the choke, start and rev the engine a little for about 2 minutes and see if the engine runs when you release the choke.
Adjust the needle valve or idle screw, you can take the carb off easily and put a can of carb cleaner through all its ports and holes.
