It's easy enough. This may not be the right way but it works for me. First loosen the bolt at the neck of the carb. Now you should be able to slide the carb out. Then find your high and low speed needles. Your HSN will be where your fuel line goes into your carb. Your LSN should be the screw in the center of the throttle arm. Take a small flat head screw driver and turn the screws clockwise to tighten them. You need to count the number of turns it takes to tighten them. Write down this info so you can set the carb back to running. Then take out your needles and soak them in denatured alchohol.there's a few more pieces inside that come out easily if your comfortable enough to go for it. If not you can also run it thru the carb to clean inside. While you have it apart is also a great time to seal it. There's plenty of video on you tube about that and alot of other useful info. And when your stumped you can always find an answer here. Also taking pics along the way can help you remember where pieces go. Good luck
