How to remove carbon deposit from Jinbei engine?

At present, there are several ways to remove carbon deposits: if there is too much carbon deposits, it is best to spray cleaning liquid from the spark plug hole to wash away the carbon deposits in the combustion chamber. Use special equipment to pump a good carbon remover into the combustion chamber from the spark plug hole, so as to melt the carbon deposits in the combustion chamber, and then suck these liquid carbon deposits out of the spark plug hole. This method is the best at present, and the price is around 800 yuan.
