Were they stuck with gelatinated gas or internal rust?

Just before the trip, I replaced all the tires. Four corners, and the spare. I got them at Firestone, but what I put on was dictated more by "what was available near the size I wanted" than anything else. The original tire size was 175 SR 14, and the web says that back then, when the aspect ratio was not spelled out, it was 78%, So using that, the original tires were 175-78-14. The closest to that size I could find near me was 185-70-14's, which is a tiny bit smaller than the original size, but only about one percent different. Close enough considering the availability. I went to Firestone and got "Suredrive Touring A/S 185/70/14" on all four corners and the spare. Nothing special, but very close to the original size. And the date codes were from late 2024 which was a whole lot fresher than the tires that were on there before.

Is it for the 260 in your cars owned or is it a ZX as the TECH FORUM category you chose? Here's wiring for a 260. There's a lot of info in the RESOURCES category up top of the home page

Last time I messed with this, I tried to use off the shelf screws and I could not get enough mass packed into a small enough package. I've found that 4 grams is a good amount of mass to get the float to sit level at equilibrium, and the wood screw just didn't weigh enough. Here's a failed attempt to use a brass wood screw instead of making my own weights from scratch. Pic of a wood screw chucked up in the lathe, narrowing the head, The process of narrowing the head worked fine, but the amount of mass remaining wasn't enough. I ended up making another pair of weights from scratch. Here's a pic of what didn't work out:

The RPMs should decease when lifting that piston, almost dying out. Lifting the piston disables that carb then you are running on the 3 cylinders the other carb feeds. That's what mine does anyhow. Try reaching in and lift the piston itself instead of pushing those pins down. Your needle height may be off from the rebuild with the needle height set screw? Remember raising and lowering is viewed from the bottom of the car. Turn the nuts towards the fender to lower the needles. Read the section on SETTING MIXTURE.

Still in original packaging. $10.

Phot says it all. Sand, paint and ready-to-go $25

I just this morning realized my '72 has all Nissan glass except the front, PPG. That means it's not 100% but a busted windshield on a 53 year old car isn't a deal breaker. It does have the blue-ish tint sun visor.

Glad you came to ZCON and gave me some inspiration on my future engine! I got a pic of our cars together and one of yours at the show Saturday. Hope to see you again at a future event!

😎

Glad to be alive . I’m a lucky guy for sure . It’s fancy but it’s all business too:)

Here is the SU tuning kit mentioned in post above. I just checked on eBay and they are available for $40. The small aluminum fitting laying on top of the gray package is the one I was referring to.

This is for you, not your car.🙂 Something I figured out after getting older and working on these cars. You can help your back when doing all that tedious engine bay stuff by simply running it up on a set of ramps or raising it up and using jack-stands to get the motor up so you're not bending over all day. Another thing I had learn the hard way was resting my elbows on the fenders would cause dents I ended popping out with a suction cup from HarborFreight. Cover the fenders with anything like towels or paint drop cloths using magnetic bowls that hold all the fasteners. I'm about to adjust the valves on mine. I use a set of Rhino ramps to get my lowered 240 up to, looks like about 38". Just a courtesy bit of advice you probably figured out way before I did and it really helps. Have fun!

Very cool! I love my ZCG brake kit. The KW stuff is probably amazing, but I can't stand the purple and yellow:)

You are right! Mechanic should get this engine running with pertronix ignitor module 1761, 1.5 coil and 1.5 ohm ballast.

Photos are of the original N33 exhaust manifold I removed from my 73. Replaced it with an earlier one when I went to round top carbs. I confirm you need a different downpipe. I was able to swap my 73 downpipe for an earlier one.

Hi Site Been a while….not sure, but whatever adds .080 inches….if they are .040 inches, 2 would do. Don’t hesitate to call Eiji….tell him you’re my cousin and if wants to keep eating steak at our house, he needs to be nice! 🤪 He’ll sell you the right stuff.

Ok thanks but would you know the casting number on the OEM exhaust manifold please ?

I believe he mentioned 10 plus years.

I've been stuck on this album for a couple of weeks now. I'll put on something else and after that finishes I'll say to myself... Let's give John Hiatt - Walk On another play.

I do, I ordered another from Nissan to replace mine. When I get back in town from Boston, I’ll post the p/n. Can’t remember if it was superseded.

I live in arizona... i bought it and it just arived in less than 24 hrs. fastest turn around for a relay i thought i would have to wait 1-2 months for.

Thanks Matthew for a great write-up =) Here is my tiny contribution to it: You were wondering about the Thermal switch 22110-E8000 and stating that it's probably for the automatic model only. I found information which connects it also with the manual model, with the emission control device (EGR) to be more precise. It can also be found from the -73 wiring diagrams (both manual/auto). Please see pictures below: Keep up the good work!

It's a EX-mouse.. 🤣

Thanks for the mention! I just updated the thread as I’m diving head first into the AFM rabbit hole. Some tips I picked up on my journey: - Clean all the electrical connectors to the sensors (also the bullet connectors in the harness). - Measure the resistance to the AFM air temperature sensor and the coolant temperature sensor to make sure there within spec (coolant sensor is one of the most important sensors in the EFI system!). - Buy or borrow a timing gun and make sure the timing is set correctly. - Verify you are getting enough spark (right type and gap spark plugs, distributer contacts in good condition, ignition coil resistance within spec (0,8 to 1 Ohm)). - Install a wideband O2 sensor with gauge (cheap Chinese one is good enough for now) or if you don’t have a bung in you exhaust buy an exhaust sniffer so you can measure you AFR (Air Fuel Ratio). Idle should be around 14,7 and wide open throttle 12,5 I believe. - Try and see (while monitoring the AFR) if only you idle or the entire rpm range is out of spec. If it’s only idle maybe try and play with the idle air screw on the AFM to get the idle AFR back into spec. And If nothing work only then take the AFM off the car and start testing the resistance values. The number 7 pin is hard to measure the resistance so you must hook it up to a battery (9 or 12V) to test the output voltage on the number 7 pin. If you determine that that is your issue then welcome to my world! As you are based in the US maybe an AFM rebuilt offered by jdm-car-parts or Z-store is an option for you. Unfortunately I am not so it would cost an fortune to do so for me in postage and import tariffs.
