I notice also that this thread can only be viewed if signed in. Seems odd.

It seems to work as expected now, after your change. I had the settings below. Still only works this way when logged in though.

I would make sure that you have ~ 36 psi of fuel pressure. The whole system is designed around that number. The vacuum switch is probably for the vacuum advance hose to the distributor. Vacuum advance is turned off on the manual transmission cars in gear 1 - 3, I assume for emissions. I would just bypass the switch and run full time vacuum advance. The stalling might be because the plug has fallen out of the bottom of the AFM. That happened to me once. Those funky wire clips on the plug are hard to get fully seated and they didn't leave much slack in the harness under there.

p.s. this really does seem like an AI training exercise. Commenting for the paranoid... The robot brains are manipulating us.

Here's a thread focused on the problem @Captain Obvious Points - behavior when you're logged in is not the same as behavior when you're logged out. When you're logged out it doesn't matter what you click on all you get is the first post of the thread. For whatever reason, when you're logged in, clicking on the "X replies" button on one of the main pages takes you to the last unread post. Clicking on the "X time ago" takes you to the first post. This is different than the way it used to be. And, in my opinion, does not make sense. As illustrated below. If you're on somebody's profile page, logged out or logged in, and click on the "X time ago" button it takes you to the last unread post. So, although this makes sense, it is not consistent with the behavior from the main topics page. The buttons do different things on different pages. In sum, often when you click on a button, you can't be sure of what will happen. The result is lots of extra clicking and scrolling. As far as what's normal, I roam around a variety of different forums and having the ability to go straight to the last post is normal, logged in or not. And being able to tell what will happen when you click a button, by the label on the button, is common practice. These comments are meant to be constructive. I know that designing and managing a forum is difficult. But, letting problems slide does not really help with the health of the forum. Example - I just went over to the Hybridz forum, not logged in, and clicked on "13 hours ago" from the main "All Activity" page. I was taken to the post that was made 13 hours previously. As expected. That's normal.

Are you on your phone? Maybe phones handle the site differently. I am using Windows 10, Chrome browser, HP laptop. The first image I posted was from the "Topics Last 30 Days" page.

There's nothing to manage. It's just a single thread in which to talk about Z's that are being sold or have sold. As opposed to multiple individual threads. If you read back through the posts you'll see that the concept works. Even Mike has commented here.

That is a "colder" than spec spark plug. Might be why the electrode on 1, 2, and 5 are dirty. The white ash on 3, 4, and 6 looks pretty good, but still on the cold side. Have you adjusted the valve lash? It looks like you have some cylinder imbalance. https://www.ngk.com.au/technical_info/heat-range/

If I click on 3X minutes from the main page I get taken to the first post in a long thread. If I click on 3X minutes from the poster's profile it takes me to the last post. Weird.

The injectors open after every third spark. Spraying half of the fuel called for. You can test by spinning the engine with the starter or by disconnecting a wire from the coil and tapping it to its terminal quickly, with the key on. There will be a small spark each time and one of the spark plugs will spark so be careful. Every third tap should cause a squirt of all six injectors.

Hate to complain but this inability to one-click to the last post is really a pain. And having the first post repeated on each page is too. Very cumbersome. Anyway, the 77 Turbo Z had an $11,000 Rebello engine installed after it was bought for $25,250 in 2018. Plus another $25,000 to have it all put together. $61,000 just to break even. Will it sell? Doubtful.

Interesting 77. Looks like the funds went toward the engine. Rebello Racing 3.0 with turbo. That exhaust pipe though..whoa.

Here's a link to a US source. p.s. has anyone else noticed that people seem to be leaving words out of their sentences? You can figure it out but I've noticed it across the internet. It must have something do with writing on a video screen or something. Some kind of odd mental glitch. Very powerful what? Where's the subject of the sentence? "The STM PRO !

The widths vary between brands. Just make sure that there is no groove worn on to the sealing area of the crankshaft. The seal does not have to be worn out to cause a wear groove. I just did a repair sleeve on a rear end pinion shaft. Big wide wear groove, not the typical thin seal spring wear.

Interesting. Where does this hose go to? That's the one that would go to the bottle.

Yes, it's strikethrough. Couldn't remember the name. It's here in the first box, but not the Edit box. Weird. I had one on my 76 but maybe it's an AC system only thing. I had AC.

The check valve is designed to let air pass out of the bottle and in to the intake manifold, (darn it, I knew I'd do that), but not from the manifold to the bottle. The hose with the check valve is the one that loops around to the tiny nipple on the top of the manifold. Suck on the valve to determine which end points toward the manifold.

Should work fine. If there's no leak you don't really need to add coolant. The ability to hold pressure will tell you. But if it doesn't hold pressure then you'll need to add coolant to see where it's leaking from. Unless you have good ears and can hear the air hissing out. I'm going to guess though that you might have problems getting the cap to fit correctly. Just the odds, the right size and fit might not be in the kit. You might get lucky though.

That's a lot of money for a one-time test. Why not just fill it with water, start the engine, and see what happens? Worst case you spill some water in the cabin. Put a towel under the valves and cleanup should be easy.

What testing method will you be using?

The system pressure will equalize without opening the valves, there's coolant on both sides. If you start the engine and let it get to temperature you'll generate pressure. The main concern would be that if there is a leak, it will be hot coolant instead of cold.

They can be switched. There's no mechanism inside the tank. The check valve is important though. Be careful with the hoses, they are an odd size and tend to split because they're so old. I spent a lot of time fixing mine, as they kept splitting at the ends, then the check valve went bad. Overall, it was a pain keeping everything working right.

I'm the one that reported my car(s) would not start with the tachometer disconnected. Actually, if I recall right, it was two cars, my 76 and a 78 parts car that had a good engine. The 76 phenomenon went away after I changed to an HEI ignition module. So, it seems to be a thing only with the factory ignition system. So, basically, if you try to start it without the dash installed and it doesn't start, don't freak out. You might just be the confirmation case. Good luck. One other thing to be aware of is stray wire ends that might be powered with the key on.

Just for fun, here are the bulb specs from the Owners Manual. Can you show a good picture of the type label on one of your bulbs? Just curious. Today's 57's seem to be slightly larger than yesterday's and don't fit the space very well. I don't think that 57X is available if I recall correctly, except for NOS eBay stuff.

This old thread might be helpful. It has links to other useful threads also.
