When you unscrew the top of the carb you pull out the needle with the spring, washers and piston attached. Holding this unit in your hands you can depress the spring so that the cable can be easily released. Then you can work on the C clip easily. It is just a matter of practice. To change the C clip setting now takes me about 4 minutes from start to finish. It's just a matter of practice. Use both hands when depressing the spring.Does anyone know the Right way to take the spring out of the slide so that the c-clip can be adjusted properly on the needle, and the c-clip reinstalled? I squeezed the spring open and pulled the needle and c-clip out, my way, and now the c-washer is on my computer desk. Any help is appreciated. Thanks.
