Got a carb syncing tool. This is what it told me.

I may not be awake tonight, unsure. I woke up at 1am after waking up randomly over the course of 3 hours, and have been awake since.
I do have Duo on my phone.

I could scrape the stuff off, but I'm worried that will just bring back the air leaks. There's one screw hole that I can't use a normal screw in, as the remains of the old screw are stuck in there, and no amount of Liquid Wrench, screw extractors, or left-handed bits got it out, so I drilled into it with a self-drilling screw. I don't think I can remove it anymore, or it may not bite.

I saw this earlier and already sent a message to him that I don't feel comfortable trying to adjust his valves knowing that boot may not even seal properly. In my mind, he needs to look at replacing the head or parting out the bike.

So far it's sealing, at least according to the starter fluid test. I haven't been able to find any heads yet. Even without the sealant, it still sealed half of the time, it depended on how careful I was putting the carburetor in. If I jostled the #2 boot too much, it wouldn't seal.
Instead of gasket sealant, how about a gasket sheet, where I can just cut to fit? No risk of getting into the engine, and that should solve any leak issues.
I had originally thought of trying to get the remains of the old screw out, then rethreading the hole. The metal surrounding it is still intact, there's just a big chunk of the old screw still in there.

I'm not one to give up on things others consider a lost cause. People doubted me, that I could live independently, which included getting a license. People doubted my bike, saying it would take hundreds of dollars to get running again. Well, I got it running for less than buying the next cheapest bike around ($800). And I've heard of crazier fixes that still worked.

I have two other project bikes that I literally acquired for $25, the price of title transfer in Iowa: A 2004 Suzuki Intruder VS1400 (which I'm not ready for), and a 2001 Kawasaki Ninja EX500 (which may have a blown head gasket, and I'm not really a sport bike person). Both run, but have their own issues. I intended to fix them up to sell.

I don't doubt you at all. Keep up the good work.

Thanks for the vote of confidence.

And I appreciate the wisdom you guys share with me, even if it seems talking to me is akin to beating your head against a wall. I'm not trying to be annoying, I just don't want to get rid of something I worked so hard to achieve. That's like coming home on November 18th, 2013, and finding a pickup truck parked in the kitchen of the travel trailer I lived in, that I finally owned after working for a year to pay it off. If something doesn't work, I will always look for another way. I remember one of my friends and I wanted to play Neverwinter Nights 2, many years ago, but all the servers were dead, including those that accepted keys. While he suggested another game, I spent 3 hours looking up old keys and trying them, until I found a method that worked. Yeah, an issue arose, but I'm not ready to throw in the towel just yet. Because if I do, I'm stuck waiting... again. Most bikes for sale in my area cost several thousand dollars.

I got the goop removed.
Here's the hole in question. You can see the remains of the old screw. https://cdn.discordapp.com/attachments/256689074293702658/710896817742807130/20200515_114845.jpg

The idea is that I can drill the hole wide enough, and tap it, then add one of those adapters that return the hole to its normal size, then put the screw in.
Otherwise, I found a head on eBay, but it's more than I can afford right now.
