here is another post on the subject... sounds like what I am seeing as far as relationship of marks on flywheel.. based on this I should probably check timing again!
I'm refering to 6-8 in Minor service operations-Valve Timing in the 49-53 shop manual. The triangle is to be used to position the engine to do a valve timing and timing gear wear test.
I searched "triangle" in the 49-54 archives and found this from raycow: Topic #71924
"U|C (it's not UIC) is TDC at the line between the U and the C. The ball is 5 degrees BTDC and is normally your timing mark. The triangle is about 20 degrees BTDC and I believe it might have something to do with checking the camshaft timing, but I'm not certain enough to bet any money on that one...."
I think what he say's is correct.
Please have another look at my reasoning and what the manual says and let us know how you see it. It seems important to have this settled, because a too far advanced motor is trouble, and there are some contradicting opinions being advanced.
