Those are some great pics.
And yeah, it was just too cold to drive mine, but I was sure impressed at how quickly it started (once I charged the battery.) I touched the throttle until I heard the choke snap closed, and cranked, and shortly thereafter it woke up.

It was -28C last week and I wasn't gonna drive the car any distance as the roads were solid ice, but I did have to move it. It fired up in about four seconds of cranking. Those Datsun engines are legit excellent pieces of engineering. It drove fine, too.

Mine is in a totally different car, but the handling definitely improved when I put the engine in low and further back in the car. I had to make a custom oil pan to get it lower. It seemed like a good idea to drop the transmission as well, so I lowered it half as much as the engine (about 6cm for the engine, 3-ish for the transmission.) I fabricated mounts using belleville washers as the vibration isolation: a stack of six between the engine mount and the frame, and then another two above that, so the engine can move a bit in either direction. On the (datsun) transmission, because it's so light, I just had two bellevilles above/two below. Each washer gives me about 3mm of movement.
If you were worried about the driveline angle, could you tilt the differential a little?

Huh, looks like KE Motorsports, the manufacturer of that steel hub, is out of business.
I can make one on my own if I have to. I have the dimensions now, and I can cut a smooth edged keyway so it won't crack at the corners.

I bet a dollar mine are the two you list: 130/110/60 and 130/100/90.
I just last night cut the 90 down to 89 to fit an EDIS wheel.
And the steel pulley is a great idea: thanks!

What I have:
Datsun A14 in the garage, Datsun A14 in my 1975 Triumph Spitfire. The Spitfire consistently runs rich, has issues starting because the auto choke and I have arguments, and mostly I need to pass an emissions test next year for the first time since this car was new as a result of changes in state laws. So I'm heading down the EFI route. Besides, it's supposed to give a bit more power too, right?
I bought a Speeduino kit and built a simulator for it and played with it for a while, so I have some ideas about how to use TunerStudio and some rough approximations of the A14 fuel needs. I also got a throttle body from, I dunno, a Kia? It's a 1.6 liter engine, so it's about right. (I 3d printed a bunch of throttle bodies to try to get a feel for if I could cast one, but came to the conclusion that $20 on ebay to get the TB plus the throttle position sensor was a much better use of my time.)

So today I got the impact wrench out and removed the crank pulley fixing bolt. Oh hey I didn't realize that the pulley is essentially a seal. Well, that means I probably can't make one myself, because I was thinking about machining a perfect little crank pulley: just the one roughly 130mm pulley diameter, with a nice flat area I could mill into a 36-1 indicator wheel, and then an extension area for some day if I ever get the energy to try bolting on a Gilmer drive.
The toothed wheel ID is 102.3mm. The smallest pulley OD is 103.4mm. I sure hope it's a good concentric casting...

As this will be spinning fast, I indicated in the bore, not the outside, since that's what I need as the reference point. This was rotten. I had to indicate it in end to end first, and then radially, and I can't see where the indicator's touching since it's way down inside, and the indicator doesn't like the keyway. (It's okay if you can get it close enough that it only drops about 0.01" when it goes off the end of the keyway, but that takes a while to get to.)

But once I got it aligned in the four jaw chuck, it cut nicely and the wheel went on as a quite tight sliding fit. This way it'll hold on well enough that I can get the sensor hooked up and running, and then braze the toothed wheel onto the pulley to keep it solid.

B210 A14 triple sheaf crank pulley question

I have two A14 engines. Both have triple crank pulleys. They're different from each other, and neither one looks anything like the triple pulley that's on the tech wiki. In both cases, each layer is a different size. The largest one is about 130mm on both (and it's the only one I use.) One has about a 100 and about a 60, while the other has about a 110 and about a 90. They're both engines right out of what were previously stock 210's so I don't think they've been swapped. I'm mostly just curious: are these normal pulleys?

I'm trying to figure out how to mount a 36-1 trigger, and considering different ideas, and since I only use one sheaf it's pretty tempting to pull one off one of the engines and stick it in the mill and cut the teeth right into the pulley.
But eventually I'd like to put a small supercharger on the engine, and in that case I'm going to want a single sheave with a Gilmer extension on it, and maybe I should just do that now. I dunno.

I went through this again.
First thing I was wrong about : the choke wasn't closing fully. I thought it was until I got in and messed with it a bit.
Second thing, you're right, the choke pull-off isn't working. The hose to it is cracked.
So I'll sort those out.
TBH I'm kinda thinking about just reverting to a manual choke.
But thank you for the suggestions: I learned some already and if I can get the choke to consistently close all the way I'm sure it'll work better.

I downloaded the Speeduino EFI firmware recently and built up my own board to drive a fuel injection setup and was wondering how I was going to stick it on my A14... and there's an entire page just about this.

Y'all have built a really amazing resource here, and just about every time I have a straightforward question, I find the answer if I search enough.

BTW ddgonzal now that I've read through the auto choke adjustment section of the wiki, I get why you said key off.
Mine is directly wired (no relay) so as soon as the car power comes up, the choke heater begins to run.
