What are the reasons for the Fengshen AX7 not responding when starting?

[JesseDella]

Fengshen AX7 not responding when starting is due to: 1. Damaged spark plugs, burnt contacts causing weak ignition voltage; 2. Faulty dry ignition coil, resulting in weak ignition; 3. Engine oil being too thick or dirty, causing excessive resistance during engine startup; 4. Insufficient battery voltage, leading to reduced starter motor speed; 5. Worn and unsealed cylinders and valves, resulting in low cylinder pressure. The ignition system mainly consists of spark plugs and ignition coils. Spark plugs are wearable parts that require regular replacement. If spark plugs are used for a long time without replacement, the electrode gap will increase, and carbon deposits will accumulate on the electrodes, leading to ignition failure.
