I've been pulling what little hair I have left out of my head. The belt alignment procedures in almost everything I've read says to line up the nub on the rotor to the flat raised area on the rotor housing when the timing pointer is lined up with the belt alignment mark on the timing sticker on the fly wheel - after confirming top dead center matched tdc on the flywheel timing sticker. I got this concept and down to a science...... but,
But when I do this, there is not enough adjustment (not even close) to dumb down the timing to 0-3 degrees while idling in gear in a tank. It can only dumb down to 21-23 b/f tdc at best.
Then, I read a post that stated to align the cam, the rotor pulley center, and the arrow on the rotor pulley to "timing line" on the flywheel. (I assume that means where I want the idle timing to be at) I did this, and here are some pics...
I can only align it after tdc or 4 degrees btdc. Which one should I run with before I make adjustments? It will run at both spots, and I have room to adjust to the accurate timing from both spots.
What's your opinion or experience? Is the 1972 timing belt alignment different than the 73-75 engines? Or, is there something completely wrong with my engine.
