Automatic golf has low speed and high rotation speed.

It is the phenomenon that the throttle is stuck due to excessive carbon deposition at the throttle position.

Solution: the throttle and idle motor can be directly disassembled and cleaned; The air intake, intake valve and combustion chamber can be inspected by endoscope first. If the carbon deposit is not too much, you can use the ordinary disassembly-free cleaning method. If it is too much, it is best to spray cleaning liquid from the spark plug hole to wash away the carbon deposit in the combustion chamber. Use special equipment to pump a good decarbonization agent into the combustion chamber from the spark plug hole in the form of foam, so as to melt the carbon deposits in the combustion chamber, and then suck these liquid carbon deposits out of the spark plug hole, so that the cleaning effect can be known from the color of the sucked material, and at the same time, check and replace the gasoline filter element.
