There was quite a lot of spitting back through the carbs. That suggests to me that the inlet valves were open when the spark came. That usually means: 1 - ignition timing is well out, 2 - valve timing is out, or 3 - inlet valves aren't fully closing.
Oh dear Nat it seems you are reaching the end of your tether, persevere it'll be worth it in the end. You've had the whole thing in bits there could be a plethora of potential faults here, but I’d definitely check your timing settings. One problem at a time, get to the non working start button afterwards.
I think it almost started at 5:35, didnt it? I believe it is a wasted spark and I watched you do the timing - it looked fine. i'd double check valve clearances, compression test and new plugs. oh and I know others have mentioned about doing a test on the valves before you reassembled which is too late now , but I remember Ryan in his garage doing a leak down test with a balloon on his assembled engine
The Cv carbs are a bit of a pain, but with no firing even with easy start i would check your timing again, i do think hondas use a wasted spark ignition. The other thing to check is the engine grounding to earth, ive had a spark on a cover before but not on the head.
Valves out by 180? Timing sounds more likely, you've got spark, you've got compression, you've got fuel (if nothing else you've got startyabastid®). Plugs on the wrong coils, or does it run a wasted spark? I forget, haven't had a superdream since 1986 or so.
Do a compression test,I sed before u fit the head to pour petrol into the valve bowls,if it leaked then the valves aren't seated properly.but try a test anyhow now it's built & use new plugwith choke on as they flood easy ... Good luck..Ian🤞
They take forever ever to start after a rebuild mine was same check all earths are clean even wire on too starter make sure it’s tight sometimes the starter can not be strong enough mean it’s fooked I find they start better without giving them throttle full choke they don’t seem to like both starting up also they carbs is a pain in the arse had mine off so many times I forget just persevere all ya do 😂
Loop out the cut off switch and get a decent battery on, 90% of carb issues are electrical. As mentioned double check your timing isn't 180 degrees out.

Persistence pays off.
If it's right, it should start right off the bat.
I like your new opening sequence 🤙

We just need space... :)

I have stopped doing projects now. Just do maintenance on my 3 bikes. Just keep going Nat you will get there mate 😡🛠🏍😭❤️
🏍👍👍👍👍
Ignition timing, I use propane gas from my blowtorch if carbs/fuelling is suspect- it's cheap. Keep at it and the engine itself seems happy enough.

Bloody bikes lol.
Some restriction on the carbs possibly. It looked like the airbox was open with no filter on test.

That is spinning over very fast which suggests lack of compression! do a test.

when I had mine in 1983, after a 2 week holiday, it would not start off the starter motor - only went off a bump start

Plug leads transposed ?
Sounds like ignition is 180 degrees out. Are the coils correctly wired? Can you swap plugs leads over?
