What if Futian light truck emits black smoke?

It is suggested to clean the throttle valve, replace the cylinder pipeline and spark plug, and replace the oxygen sensor. Due to the poor fuel system and air intake system, the mixing ratio is inappropriate and the combustion is incomplete. In this case, there will be a series of problems such as black smoke, detonation, insufficient power, unstable engine operation and jitter. It will directly affect the normal running of the car and even cause more serious failures.

Treatment method:

1. Carburetors are basically old now, so check the aging degree of carburetor and other parts frequently. Carburetor car is different from EFI car, so it should be maintained and adjusted frequently to form a good habit of using the car.

2. The EFI vehicle shall check the cylinder pipeline every 30,000 km and the spark plug every 1000 km. If there is any problem, it should be replaced in time.
