Check the battery method. Check if the battery has electricity. The whistle can be judged by listening to the sound. If the sound is loud and strong, it means that the battery has electricity, and vice versa. This requires charging the battery or replacing the battery. Look at the platinum gap method. When viewing the platinum gap, open the distributor cover and pull off the split burner to see if the contact surface is clean. Like a smoked one, it can be rubbed with a new paper towel until it is clean. When installing, pay attention to whether the distributor cover marking is correct. Check ignition coil method. Disconnect the high voltage line from the distributor interface, that is, the high voltage input distributor line. Then, insert a screwdriver into the line, hold the handle with your left hand, and place it close to the line of fire by about 1 cm to observe the fire. The fire is normal and blue. If the fire is weak, the ignition coil is faulty. You can use the hand to feel the temperature. Touch the ignition coil by hand, the micro heat is good, overheating or hot hand indicates that the coil is bad and needs to be replaced. Observe the spark plug method. If the coil is still in good condition, you need to remove the spark plug and observe whether the gap is too large, whether the core is loose or not, whether there is carbon deposition, or whether wet or not. The gap is 2 mm. If it is wet, it is "flooded" and it is caused by excessive throttle. After drying, put it back and have carbon deposits to remove. Adjust the method of catching fire. The car does not catch fire. It may also be the wrong ignition time. Loosen the distributor fixed screw inspection. Slightly rotating the distributor, commonly known as "catching up fire", turning clockwise to retard the ignition, and counterclockwise to advance the ignition. After adjusting, you can light the fire, fix the distributor, and you can hit the road.
