Is an ignition advance angle of -10 normal?
1 Answers
An ignition advance angle of -10 is not normal. The reason for a negative ignition advance angle is a malfunction in the knock sensor. Below are the methods for adjusting the ignition timing: 1. Adjust the gap: Check the contact gap of the damaged electrical components and adjust if necessary. The normal contact gap is 0.35 to 0.45mm. 2. Adjust the cylinder piston top dead center: Manually rotate the engine to position the first cylinder piston at the top dead center of the compression stroke. The method involves removing the spark plug of the first cylinder, blocking the spark plug hole on the cylinder head with a finger, and turning the crankshaft. When atmospheric pressure is felt, slowly rotate the crankshaft to align the timing mark or pointer with the specified symbol.
