Here we go again. Its acting up worse this time!

Where the gas line enters the carb is that brass fitting. Un hook the fuel line and pull that brass fitting out. That's the needle and seat. You'll see how it works once its out After its out blow it out with air or carb cleaner. Some times you can't even see the dirt bit its enough to hold it open and flood it.

Double and triple check the oil. Gas and bearings don't get along well.
