im almost 100% positive i have it completely correct... the little
hash mark lines up EXACTLY with the top of the gasket for the valve
cover, the 0 on the flywheel is looks like "(" as it it perfectly
lined up w/ the marker on the bell housing as the bently states to
do, and the distributor is spot on.
now, i did try moving it a tooth counter-clockwise, which should be
retarding it, correct? i did not, however, try advancing it a
tooth... but if i advanced it a tooth, then that would put the mark
on the cam gear way further down compared to where it is supposed to
i guess i could try advancing it a tooth and see if that helps at
all... i'll go do that now, and report back..

yeah, its the same cam i pulled out of the old head... it's a stock
it's not that it wont go above 3500 rpm, its that the power totally
shuts down above about that point... it's like im short about 70hp...
now, i have not adjusted the mixture, though... there is actually a
plug on the mixture screw, it seems,and i dont have a multimeter that
could help me anyway... <sigh>... but, could a mixture adjustment
cause these particular symptoms? im less worried about the idle as i
am about the lack of power...
and lemme know if you have any other info...
