The carburetor problem ... according to your description, it should be caused by excessive oil supply in the carburetor. 1 See if the choke is forgotten to close. 2 Check whether the air filter element is blocked. 3 Clean the carburetor to see if the oil level is too high. Whether the oil needle is loose from the main metering hole. None of the above is abnormal. Consider replacing a new oil device for testing.

None of the above is a problem. Considering that you stated whether there is a problem with the circuit when shooting, check that the circuit is not on fire. Replace the spark plug because it is rich in grease and the electrode does not catch fire, so it must be replaced with a new spark plug. Mainly the replacement of high-voltage bag and igniter. The problem should not be too big. It's a new car after all.
