2) by marks you mean the dots on the two gears? At each other I believe. I was using a manual for rebuilding and I set it up like the pictures in the guide, pretty sure they were pointing at each other.
3) yep...there was also something about turning it 90 degrees and then there being 21 links between the points. That also checked out exact.
Really regretting not taking any pictures now..Lesson learned!

Lol, no worries. We all have wished we took pics of something only to later really "need" them. If for nothing else, peace of mind.
yes, the dots must sign up, point at each other. The reason this is vital is because the keyway/woodruff key keeps the gear (cam or crank) located on the shaft. If you put it on but the dots are a bit off, your cam won't be in the right spot.
You must put the #1 cylinder to TDC, put the gears/chain on their shafts and have the dots be aligned. If the dots don't line up you'll have to carefully rotate the camshaft to let that happen. It's kinda a three hand juggling act to get the dots aligned, the chain/gears on, and not let anything move. As you're discovering, due to the amount of work to do the chain, it's way worth it to make sure, 100% beyond a doubt, that it's right.
My understanding is once your install it and are satisfied it's correct, you rotate the engine by hand for several rotations. If you run say, 4 complete rotations and the timing dots are still aligned you should consider it good. The slack on the back side of the chain (passenger side as you're looking at the motor) is what can make it off. Thats also why you should always rotate the motor clockwise and never back it the other way if you go too far. If you miss your mark by just a little bit, don't back up. Just rotate another full cycle and stop when you need to.
