[QUOTE="scdmarx, post: 58690, member: 92"] Interesting, and a good point. A loose belt can cause cam timing to be 1/2 or one tooth late, as well as chattering back and forth. But I guess I'm just not getting the full picture yet. The timing light is triggered to flash at the moment current passes through the plug wire. You point this light at the mark on the crankshaft flywheel. I can't put it together in my head how the ignition spark moment is affected by the cam belt timing. What drives the advance unit drive shaft at the pulse generator? I can easily understand this with the earlier points driven on the end of the camshaft. [/QUOTE]
