Your compression test would seem to rule out anything mechanical in cylinders one and two. And yes, front carb supplies all three front cylinders, so I would not suspect a "no fuel" issue. How confident are you that the carbs idle settings for the carbs are where they should be - so both carbs flow the same amount at idle? And, when revving? Spark plugs can be dead right out of the box. I'd move plugs around and move plug leads around with them. I'd try swapping known good, perhaps from six to one and from four to two and vice versa. I think a Z engine will have a very hard time running if it has two totally dead cylinders. They may be intermittently firing a bit. So, new plug wires, new plugs, and new distributor cap?

I'm still trying to figure out what caused this kind of damage 🤔

You can back out combustion chamber volume using compression ratio and displacement. The 1972 FSM has the numbers. And if you have the head and block in hand you can take some measurements.

Do they have good grounds? Have you tried to bench test them?

Hi guys, this week i sold my 240z! It needed a good service as the engine leaked some oil, the body needed some work and.. i don't have the energy to work on it i will now concentrate on the engineroom of the 280zx i had restored in the past years.. I kept my self made mahogany steeringwheel and gave the new owner the rear wheel arches that i had stored on my attic with the car and some other nice parts to make an nice driver car for every day. As you can see in this pic the car has glassfiber rear arches and they are not original. As i said, i will now with some help of a friend, going to work on my almost ready 280zx! He also helped to get the lighting ready in my carport as he is a electrician as i am also! I finished also the air to air heat pump in my garage, so we can work on the 280zx coming winter. It was a bit difficult to let the 240z go but i had it for 27 years, and drove it for 25 years! It was a blast!

I think that I saw that or something similar on PBS or one of those channels. It was more focused on the main guy with the mustache. Rick Hall. Pretty fascinating show. https://en.wikipedia.org/wiki/Rick_Hall

I suppose it could also be bedliner.

Thank you for info. Will locate the correct sub's. CLSD R200 diff came from a large parts sale. Someone may have mixed parts and installed the incorrect sub's into the carrier to sell as a complete diff.

Here in Panama we use 95 fuel. Mechanic advised to use an octane booster. The thing is how much in half full 16 gallon tank? The whole can or half and then fill up the rest of the tank with 95 fuel?

Before you get too far you might as well find the ECU. The brain box. It's over by the driver's left leg, behind the kick panel. It controls the injectors. Unless you're planning to run carbs.

I'm a big fan of having a vacuum gauge on the balance tube (and plugging the emmissions holes). If the engine isn't healthy, it doesn't matter how the carbs are tuned. Compression, Timing, then Carbs. The vaccum gauge is a wonderful tool to see the health of the engine. I

Not odd at all. It's the same reason that British Standard threads were used on a "Japanense" car in the 1950s and early 1960s. Nissan's tie-up with Austin. Wait 'til you hear about Imperial wheel diameters and PCDs... https://www.nissan-global.com/EN/HERITAGE_COLLECTION/short_story/en_p13-01.html

Hello - I got them available- let me know if you are still interested

I used aluminum aircraft rivets - and like your pop rivets, I should have used a semi-tight washer on the squishy end. The sheet metal on the contacts is really thin. I also "re-squished" the (original) rivets on the bulb holders.

Sounds like you're saying things have been just fine then something changed. As opposed to the brakes having always bothered you. If it was mine I'd find the source of the sudden problem before "upgrading" anything. Otherwise you could add the upgrades and end up with the same problem, never solved.

I have used the Zcardepot style pans in the past. It is a lot of work getting them to mate up well to the tunnel. If it were me, I would get the KF pans. I think they are better pans and will give a better finished product. You may not care today about an OEM look today but you might in ten years...
