Is a different needle needed for a 2.8L?

SUs don't have a function like an accelerator pump on a Weber, which is one of the reason Webers have a slight edge on immediate acceleration. The spring and oil are about damping the piston to keep the engine a bit smoother instead of always micro fluctuating with engine speed changes. Spring and oil work together to set how much it takes to get going and at what rate it goes once it is going, respectively.

Springs would only effect acceleration right? What was the final consensus on the same needle for L24 vs L28?

It's all about what you are willing to pay. That price isn't far off a set in good shape, as determined by internals more than dust on the outside. A lot of patina can show up on a carb that's mint where it counts...

It'll be a good question for Eiji.

42 DCOE, so medium ones.

I've been emailing with Eiji and I'm wondering about carbs. Is anyone running one of his stg 3 running a Weber DCOE set up? If so, how'd it go? What sort of jetting did it take? Did the carbs let you reach potential on the dyno?

I'm on 42 DCOE and unlike all the online Z posts Des Hammill says the F7 is the "go to" emulsion tube.

I made a number of incremental changes back and forth on ilde jets and mains trying to get it right. It got me into the ballpark, but I only nailed it down once in added an AFR meter. My main "ah-ha" was when I switch to an F7 emulsion tube, which allowed me to find a sweet spot between way too lean and way too rich. It moved my progression point and let me run a bigger main jet and a smaller idle jet. I haven't dyno'ed my final setup, but it was driving great.

That's a fair bit different than what works for me on a L28 e88 combo. DCOE 42 though... Choke 32mm 2nd vent 3.5 Main 135 Emulsion F7 Air 165 Idle 55F13 Pump 40 1.5" air horns Elevation 3,500' A stumble off idle was my main problem and what most of my changes were made to address. The 1,100rpm to 2,000rpm was atrocious when I started.

Mike (Banzai) doesn't have a '73 on his website. Mine came from ZedSaver. Sent from my SM-G981W using Tapatalk

I picked up "1973" emissions decals for the underside of my hood. They look a lot like my 1972 decals, but a bit different than whats under hood on the '73. As it turns out there was a change late '73. Has anyone been able to source late '73 stickers? Sent from my SM-G981W using Tapatalk

I can say the JDM-Parts 432 reproduction radio delete pockets fits like a glove. Slotted in immediately and the bolt holes lined up nicely. A bit pricey for a pocket, but cheap compared to trying to find a proper radio and plate. Sent from my SM-G981W using Tapatalk

Has anyone used the JDM Parts radio delete pocket? I'd like to pop one into my '73 and wanted to check fitment. Thanks. https://jdm-car-parts.com/products/reproduction-radio-delete-pocket-for-fairlady-z-z432r-datsun-240z?variant=25008521737 Sent from my SM-G981W using Tapatalk
