1. Remove the carb from the engine according to your manufacturers directions, making sure to remember where all the linkage rods and springs went.
Be carefull when removing the carburetor not to tear the intake gasket. If your gasket is damaged replace the gasket. Look up gaskets for your model click here
2. Carefully remove the fuel bowl from the carb body which may either be a bolt or a high speed mixture screw holding it on. And be prepared for some gas to come out of the bowl.
3. Push or pull the float hinge pin out so you can remove the float and the needle valve assembly. Be careful not to damage the float or lose the needle valve or retainer. They are very small and easy to drop.
4. If your carb contains an idle mixture screw remove it along with the spring. If your carb is equiped with a main jet that is removable you can remove and clean it. I recommend using a carb screwdriver for removal of the main jet, a regular screw driver can damage the soft brass jet.
5. Now you are ready to clean the carb with a good carb cleaner. If you like you can soak the carb parts in cleaner but for no more than 10 minutes. Then wipe them clean or blow them dry with compressed air. Spary the carb with cleaner paying attention to all the holes. Then blow the carb out with compressed air.
6. Reassembly is just the opposite of what you just did. Be careful to put everything back where it came from. If your carb has any adjustable mixture screws, when you first re-install them turn them in all the way then back out 1 to 1 and a half turns and that will get you to the point where the engine can start. For specific tuning of your carb, consult your manufacturer for info.
