Carburetor backfire is typically caused by an improper air-fuel mixture, often due to a lean condition where there is too much air and not enough fuel. This can lead to incomplete combustion in the engine, resulting in unburned fuel igniting in the intake manifold or carburetor. Other contributing factors may include ignition timing issues, vacuum leaks, or faulty spark plugs. Proper tuning and maintenance of the carburetor and ignition system can help prevent backfire.
