I noticed I’m having some brake issues so I retired the balance tube for now. Once I get some of the must do things knocked out I’ll revisit it. It looks nice in the box, though. 🫩

Is your tachometer connected, with the inline resistor in place? I had found in the past that my 76 and a 78 parts car would not start if the tachometer was disconnected. It appears to do something to the signal on Pin 1. I never figured out what, but I did confirm it a couple of times. On the 78 I had the tachometer out and on the 76 I had the resistor removed which disconnected the tachometer.

Starting fluid worked, engine fired up for two seconds. Tested injector pulse just now and drops form 12.5 to 10.4 both sides of the pin and no pulse. Tested the coil negative terminal 12.5V key on and jumping voltage while cranking.

Seems like the main question is "what happened between then and now?" The cracked AFM hose could stop the AFM from functioning, but the engine should stil start for a few seconds on cold start injector fuel. Maybe your spark is too weak. Are you seeing s strong blue spark or a weak yellow spark? You might try starting fluid to see if you can get it to fire for a few seconds. Another possibility is flooded/fouled plugs. Have you pulled a spark plug to see how it looks? I'd do that, it's easy and quick.

I think if the throttle blades close enough at idle, allowing pcv to function it could work, but then they would tend to stick. Maybe the SU's close off more? I have a patented stack filter, that I am working on, that if done correct, it would be a great place for the pcv to go. I never found a balance of non sticking throttles and working pcv.

Got 12v on Pin 1! Haven’t got around to test injector control, had to order a test light. But wanted to show this, how likely is this cracked AFM boot the cause of the no start? I just ordered a new boot, will be arriving Thursday.

Have you put a vacuum gauge on the balance tube to see how the vacuum looks? I'd try it at both your more centralized PCV connection, and also at your brake booster connection on the end. Just to see if you can glean any useful info from the gauge?

PM sent!

@duffymahoney , You’re right. Mimics a vacuum leak. I have a theory about what’s going on, or at least why it doesn’t do what the balance tube on the SU manifold does. With this, you have all three intake runners connected, so each intake stroke is open to five other runners. With the SUs, the balance tube isn’t on the six intake runners but is up before each half splits into three, so in that case it’s balancing three with three, rather than one with five. In other words, it balances 1, 2, and 3 with 4, 5, and 6. This one tries to balance each individual runner with all of the other five, so you have to have way more vacuum as a result. Maybe narrower runners and a smaller internal balance tube volume would make it work, but I doubt it. I thought initially it would be the PCV valve causing the problem but it didn’t change when I plugged that port. I’m going to save the PcV valve experiment for a later date when I move to a cold air intake. I think putting it on the back of that, the same way the valve cover vent hose is on the SU air filter, would be the only way to do it without expert engineers figuring it out. I’d like to know how they made it work on the new Nismo head, though.

fair point

Seems like a lot of extra tension on the cable. Gives you more flexibility on how tight you want it.

That is a Great Deal!

This is a fun, affordable way to get into vintage racing. Tom Dockery will be racing in “Little Butters”: “Little Butters”, our 1991 Vintage Spec Miata that will be available for rental throughout the vintage race season. Contact Rob at ZCG for details. Since this is a new build for I drove it for the weekend to make sure it was sorted and ready to rock for any client that wants to enjoy it. It has a competitive race engine, Penske shocks which are the current suspension for SCCA Spec-Miatas. Just to pay tribute to how wonderful Mrs. Butters Z (our Series 1 shop 240z) is, we painted it Safari Gold. It’s nickname is Little Butters, Josh likes to call it “I can’t believe it’s not Butters” and then we picked the number 23 because we are Nissan dorks. http://www.zcarblog.com/wp-content/uploads/2025/11/IMG_3012.jpg http://www.zcarblog.com/wp-content/uploads/2025/11/IMG_2997.jpg http://www.zcarblog.com/wp-content/uploads/2025/11/IMG_2976.jpg We will also be supporting Randy Pobst’s first National Championship-winning Miata (1992), currently owned by Ross Lindell.

Excellent! Glad it runs. I can't help with the triples

Yep, especially when someone in Alpharetta (near @inline6 ) posted an 83 5-speed that wasn't even cleaned up for $700.

Will try to upload a movie of it running. I tried twice but its 17MB. But it is running. Carbs are still not acting right. I have dead even flow through them, all the same across 6 carbs. Same jets, but my plugs are all over the place. I installed all new floats, float pins and needle and seats in all three carbs. Getting wildly different readings on float level using the Keith Franke clear acrylic tube method. I am 22mm, 25mm, 24mm from the top, which if I recall is to high on all of them. I have 29mm from the tip as the correct setting, but I have to go research it up again. IMG_8791.MOV

UPDATE: I got her running!!! New 123 is installed and at this point I can say it performs as advertised. Could not start it up for the first 10 minutes and was about ready to cuss as I spent so much time going over the manuals and ensuring all was hooked up properly. Made sure my grounds were good. Then I realized I had not hooked up the last black wire on the dizzy. Yeah, it fired right up afterwards into a steady 500 rpm lope. LOL

I don't like the really short brake pull. I prefer about halfway. That way I know the shoes are fully released and don't drag...

Sounds like a deal to me!

I let a couple of friends in the area know about this in case they know of someone looking for a 5 speed.

I have used this transmission in my Z for many years. After putting many miles on it over a number of years, I decided to rebuild it because it was grinding a bit when going into second. I rebuilt it myself using all new OEM bearings and synchronizers. I also replaced the seals/o-rings on the main selector rod. It has had little mileage added since the rebuild. It is in very good condition. I am switching to a 240SX transmission, so I no longer need this one. Price: $600 plus shipping or you can pick it up from Marietta, GA. Gear ratios: First 3.062 Second 1.858 Third 1.308 Fourth 1.000 Fifth 0.745 Not included are the speedometer cable and the series one transmission crossmember, though I will sell the crossmember separately.

Everything you said is 100% what was the case - that's pretty incredible. I got the car back yesterday (3/21) and here is the update: The right side (only) adjuster did seize after few uses due to the car sitting for 6 months (driven monthly between 5/25 - 8/25) but in reality sitting since 10/24 due to a variety of issues that needed to be fixed one after the next. Since the adjuster was seized, it did apparently warp the drum. The brake shop ended up grinding off a bit of material on both drums for some reason and then changed the shoes yesterday - and the car stops very well. Honestly, I'm fairly annoyed they didn't just replace the warped brake drum because now the e-brake pulls up about half-way instead of a quarter like it had been with the brand-new drums...but I'm just being picky at that point.
