Careful using cleaning products on carburetor engines, many of the additives for cleaning the fueling system are for fuel-injection systems only. Using the wrong cleaning product with a carburetor scooter or motorcycle with plastic float or the wrong rubber hoses will result in an even bigger problem.... As the fueling system cleaning additives can be very aggressive to some plastics and rubbers...
Can I use the cleaning solution also on my carburetor motorcycle?
