Answer:
The kit comes with the parts that wear out and usually need replacing. You just need to buy the kit. Make sure you get the "premium" kit (if available) because it is more complete. You will need some carb cleaner, available from auto parts stores, to soak parts in. Carburetor build-up can be stubborn to remove and soaking is the best way to ensure parts are clean. Soak overnight as a minimum, but it could require a few days before coming thoroughly clean, depending on the condition of the carb. Follow the step-by-step instructions in the rebuild kit CAREFULLY.
