Can ordinary spark plugs cause idling ignition?

There are several reasons:

The engine backfired and caught fire from the air inlet. The main failure reasons are as follows:

1. The mixture is too thin, which may be caused by the failure of oil circuit or air intake system. Oil circuit failure is mainly caused by insufficient oil supply of carburetor. The main reasons are: the oil level in the float chamber is too low or the oil supply hole is blocked. The failure of the intake system is mainly caused by excessive intake air, which is mainly caused by air leakage from the intake manifold.

2. There is something wrong with the ignition system, mainly due to insufficient ignition energy (high voltage line resistance is too large; Ignition coil is damaged; Insufficient power supply voltage) or spark plug failure.

3. The ignition advance angle is too large, the main reasons are: improper adjustment of distributor and other reasons.

Exhaust pipe blasting, the main failure reasons are:

1. The ignition time is wrong. Adjust the ignition time.

2. If there is water in the gasoline, replace the gasoline filter, clean the oil in the fuel tank and add new oil.

3. The mixture is too rich, which causes the unburned mixture to burn in the exhaust pipe. Check the carburetor for oil leakage and the combustion chamber for excessive carbon deposition.

4. If the spark plug is not good, or the power is cut off, replace the spark plug.

5. Check the ignition coil, sometimes the damage of the ignition coil will also cause this problem.
