How do you remove mini moto throttle restrictors?

That's an easy one! Remove the top of the carburetor. Take a small section of fuel line and cut a piece off. About a 1/2 inch will do. Remove the cable from the carb slide and slip the small piece of hose onto the cable and insert it back into the carb slide. Put the top back on and your in business. The hose acts as a governor to control the slide travel and speed.
