The trick is knowing which side of the cam gear to use. Flipping it over
as well as rotating it relative to the bolt holes allows a +/- 4 degree
adv/retard of the cam timing.
Once happy with the crank position, and the chain gear 'notch' in line
with the center lines of the cam and crank, it's the chain on the
distributor side of the engine that should be taught if you have the
gears lined up correctly. crank and cam in the right position.
rotating the cam to the right position can be frustrating at first until
you realize it's simply the #1 valve closing just before the #2 valve
starts to open.... frustrating as you can not do it with #1 piston AT
TDC. So you need to back the piston down a bit...better to move it to
the upstroke ... measure the cam center by seeing which valve opens (#1
and #2) ..if all goes well.... putting the chain on and putting the cam
sprocket up to the cam the holes should line up easily.
