What are the causes of tempering and ignition after overhaul of Nissan six-cylinder engine?

The phenomena and reasons of carburetor backfire and ignition are as follows:

When the throttle valve is fully open, the carburetor backfires, and the engine speed is not easy to increase: the situation of the throttle valve is obviously improved. The reason is that the mixture is too thin.

The engine accelerates rapidly and the carburetor backfires; The engine runs normally after the throttle valve is fully opened. The reason is that the acceleration pump is faulty.

The engine temperature is easy to rise, and the carburetor backfire is suddenly accelerated, so the situation of pulling the throttle valve can not be improved, and the engine acceleration is invalid. The reason is that the ignition is too late.

The engine is severely shaken; When accelerating, the carburetor backfired, the resistance damper was improved first, and the exhaust pipe caught fire at the same time: the engine did not idle because there was a problem with the ignition sequence.

There are carburetor backfire and engine jitter at various speeds F.

The reason is that the cylinder gasket burned through. Carburetor backfire happens occasionally, and it is not easy to backfire when the engine temperature is low. The reason is that the spark plug is overheated.

In view of various situations, take measures to eliminate faults. I hope I can help you, and I hope to adopt it!
