What to Do About Backfiring in the Exhaust Pipe?

[Leon]

Backfiring in the exhaust pipe should prompt an immediate check to see if the choke is fully open, with high-speed maintenance performed if necessary; after the engine is turned off, inspect the main nozzle from the carburetor port—if fuel is spraying or dripping, the float chamber fuel level is too high and should be adjusted to the specified range, with the main jet tightened or replaced; if the air filter is clogged, it should be cleaned or replaced. Relevant information about the exhaust pipe is as follows: 1. The exhaust pipe is part of the engine's exhaust system, which mainly includes the exhaust manifold, exhaust pipe, and muffler. Typically, the three-way catalytic converter, which controls engine pollutant emissions, is also installed in the exhaust system. The exhaust pipe generally includes the front exhaust pipe and the rear exhaust pipe. 2. The automotive exhaust system is primarily used in light-duty vehicles, micro-cars, and buses.
