The hazards of abnormal ignition advance angle include: 1. Causing the crankshaft to reverse, preventing the engine from working; 2. Prone to abnormal combustion; 3. Leading to a decrease in engine power; 4. Resulting in engine overheating. The adjustment method for the ignition advance angle is: 1. Check if the platinum contacts have any signs of burning; 2. Remove the secondary chamber vacuum hose from the vacuum advance compensation device, block the two ports connected to the hose, and let the engine idle; 3. Use an ignition timing light to check the ignition advance angle; 4. When turning the distributor housing counterclockwise, the ignition advance angle will increase; 5. When turning the distributor housing clockwise, the ignition advance angle will decrease.
