Bicyles? Ha! I always loved firing my chain backwards down the road when I
was on a motorcycle at 60 mph. At 88 feet/sec with you gunning the engine
wondering what happened, and trying to glide for distance, never dreaming
that you didn't have all your parts with you. It was a long walk back to
pick up that pesky oily, dirty chain. Usually lying in the middle of the
highway with trucks zooming by. At least I usually carried another link with
me to put the chain back on. I learned that after driving home with a link
made of twisted coat hanger wire once. I switched to shaft drive soon after
that.

All sounds perfectly normal to me. New gears and chain should be tight
enough that it's a bit difficult to hold the cam gear up and put the first
bolt in. However, there's a good deal of tension applied to one side with
the engine running, so the tensioner is still needed to take up the slack on
the other side.
Timing chains almost never have detachable links, as they're prone to fall
out with extended service. No big deal on a bicycle, but not something you
want to have happen to a car engine. Even serious bicyclists shun them for
the same reason.
