I read the tech article before.. references other valve positions to position valves for adjustment rather than indicating a specific crank position as noted on flywheel.. this is the same method I used on V8's.
my question still stands on what circle and triangle represent... I looked in repair manuals and nothing is explained as to what the marks are for.. is there any reference as to what these marks are for?
Ill try the above method this week and see where the marks line up on flywheel
