Yeah, watch a few more videos and continue to toss stuff around because it don't start, runs rough, or blows fire out of places that is not supposed to do that. Not you're fault, every engine has a basic event that makes it work, but they also have a kind of personality.
that said, you can't just put the balancer on 0* and point the rotor at an intake bolt, jamb the cap on and live happily ever after..
check each component for proper position and function,
here is how I do it,
pull all the plugs, make turning over the engine easy, find #1, we all know where that is on our cars, turn the engine by hand as you hold a finger over the #1 plug hole, make sure you're turning the engine the correct direction, I never remember so I have to look to make sure I'm goin the right way and I've done this countless times (which makes no sense in reality) still have to check myself.
when you feel the air pushing your finger, look at the balancer and you should see 0* coming around to the pointer, stop, stick a straw, or a long thin screwdriver in the #1 hole an feel for the top of the piston, let the straw or screwdriver guide you to TDC, the piston will seem like it stops for a moment, that's TDC, you can now confirm the 0* mark on the balancer, you can turn the engine back and forth to find the moment the piston stops, the balancer should be at 0* at the pointer, or at least damn close, is the balancer in the correct place? If yes move on to dropping the distributor, if no, first check timing chain slop, if minimal replace balancer.
Now install the distributor with the TFI positioned between the AC stuff amd the alternator stuff, now, about that rotor position, when removing a distributor the rotor will turn as it's lifted out, so when you drop it back in the rotor will rotate back, so you should mark the distributor where #1 plug wire is and start the rotor before your mark.
Some caps have the #1 plug wire marked with a 1 but not all.
start at TDC (confirmed!) Mark rotor postion and distributor position , remove the distributor, and you can drop it back in the same place.
Just a old guy with a lot of useless info that may or may not apply to your situation and may or may not work,
