I have a 1981 cb 750 dohc and the timing is off. Cylinder 1/4 is spot on with a strobe light, but 2/3 cannot even be seen. How is this possible? All four cylinders have spark with the plugs laying on the head but the timing is not right. Can anyone point me in a path to start searching other than the step by step process per manual in the ignition section.
