In neutral at idel, give it gas and the engine dies/stalls

Did you turn the chock off? I know that sound like a dumb question but it would flood the engine if you didn't. If you have turned it off after it is warm and this happens then your carbs need cleaning cause of some foreign mater has gotten into them. Remove the air cleaner and hoses that are attached to the back of it. Then the fuel line and the cables. There is a clamp that holds it in the intake boot just loosen it and remove the carb or carbs. The carbs are a touchy thing to clean and it will take a few hours to to this if you haven't done this before. Also get a Service repair Manuel and it would help you out doing this and in the future.
