Authentic Yamaha Fuxi (near the sea) burns spark plugs in the third winter.

If you say that there is only a burning Martian mouth in winter. Then you should consider starting the cold car after the hot car is fully started in winter (you can't put your hands on the exhaust pipe when the hot car is finished), and use winter engine oil in winter! ! In addition, you should use the Martian mouth of the factory product! ! For example, NGK in Shanghai, or Zhengchang products in Guangdong, Zhejiang and Hunan! ! You should check whether the mixing ratio is normal! There is also the worry that it will be replaced every 5 thousand kilometers. This has something to do with it.

Chemical oil itself should not be a big problem! !

Carburetors are generally 200 yuan, excluding labor costs. You can order it online. Fuxi's chemical oil is produced in China, not worth 750 yuan.

Be sure to warm up the car, ensure the use of oil in winter, and then debug the carburetor should be able to solve it. If the chemical oil is really aging, it will be replaced, but it is unlikely.

If you can't try to adjust the valve, check and polish the valve to make it burn more fully! You should also check the ignition system.
