1: I guess there is something wrong with your cylinder seal. This is just one of them.

2. Clean the carburetor immediately, clean the throttle, or clean it yourself. There is a special water agent for cleaning oil and gas. When spraying, a chemical reaction will occur and it will turn black. Wipe it with a cloth, spray it again, and then wipe it until the carburetor sprays pure white. In this way, you can clean the carburetor directly without disassembling it.

3: The oil should be changed every 2000 kilometers. Did you change it? If the oil is not changed in time, the oil will deteriorate and the color will become lighter after a long time. It seems to increase obviously after deterioration, but it is actually deterioration.
