How to disassemble Chang 'an Ruicheng 1.8t throttle?

Dismantle the oil pipe first, then the metal speed ring, and then the battery cathode. Put some oil on the fixed metal collar first to avoid slipping teeth during disassembly. Remove the metal ring of the throttle hose. After the hose is removed, the left end is the position of the throttle. Remove the negative battery, turn off the ignition switch, straighten the throttle, spray a small amount of "carburetor cleaner" into the throttle and then use a polyester rag.
