I haven't checked bowl levels yet. Good tip. Thank you.

Opening slowly or mashing it results in the same spike in AFR and engine shudder. Because I can't actually change my chokes I haven't been bothered by what they are. Are possible solutions different depending on the size of the chokes? E.g. if a choke were smaller I'd look at my idle jet vs. looking at my main jet if I had larger choke? Sorry if this is a dumb question, but I'm learning here.

Chokes are an unknown, so I assume the stock given 42 chokes are like unicorns. When I accelerate from cruising it goes 13.5:1 cruise -> 18:1 for a bit -> 10:1 on mains.

Tip in means when I accelerate. I'm using an innovates AF in the header and a mech gauge to read. I have 130 and 120 jets on the way given my 10:1 at WOT.

Reviving this thread as I'm a few years behind y'all... L28/e88 combo with bone stock, albeit fresh, internals. DCOE 42. 135 Main 165 Air 55F2 idle F15 emulsion 45 Accelerator ? Choke (haven't measured them) 50mm slide in velocity stacks Car starts and idles great, but I'm pig rich at WOT (10:1), looking good at idle and cruising idle (13.5:1), and wildly lean at tip in (18:1). My guess is a previous owner went rich across the board to mask the lean tip in as much as possible. I'm trying to get the AFRs better step by step and my question is whether success has been had to bigger acceleration jets? Leaning out my idle jet (F8 to F2) improved my driving idle, and accentuated my tip in lean spot. Waiting on jets to play some more...

Aww I'm a "/friend".

I have a stock 1-owner 11/71 that has undercoating for the most part, with visible colour painted parts (front of frame rails) in others.

With my stroker kit it'll never be the smoothest idle, which I like. I'll use the books as a starting point, once I'm confident in my fueling. Sent from my SM-G950W using Tapatalk

. Back to topic, are the textbooks' suggested numbers ok? My jetting doesn't entirely line up with the books, nor the stock carb build configuration. Yes, I saw that reference but didn't think it was right for my 3.0L L28.

Given the gap between 40 DCOE and 45 DCOE for street and track at the 500cc/cylinder might I not hit a sweet spot with my 42 DCOE? Sent from my SM-G950W using Tapatalk

They are each a No 3G (?), Type 8 (Maserati 3500 GT). 2 progression holes. No visible makings on the chokes to denote size. Sent from my SM-G950W using Tapatalk

I wonder if "numbers matching" means anything? Sent from my SM-G950W using Tapatalk

Yeah, I got lucky with the carbs the car came with. $5,000 per carb seems to be the going rate, which is crazy. Sadly, I'm a sucker for rare and cool things so I'd like to get them working before I sell them for a profit. Sent from my SM-G950W using Tapatalk

I'll check out that 24026280 page - thanks! A fun bit for me is I get to figure this out with 42 DCOE. Sent from my SM-G950W using Tapatalk

I thought you had to have throttle wide open on a hot engine for an accurate compressions test? It needs to breath between pressure readings right? Sent from my SM-G950W using Tapatalk

I've come across suggested Weber setups by cylinder cc and I'm curious if people have had success when starting with suggested textbook values? The only published Datsun specific values I've found are for 2.4L/2.6L and my L28 has a stroker kit making it 3.0L with the extra lift. Sent from my SM-G950W using Tapatalk

I have a temp setup in the engine bay. I pull power of my light and grab signal from the alternator. It works better than my mech, but I need to clean my tank and relocate a better pump to the rear Sent from my SM-G950W using Tapatalk

Here's what the little K&N look like. No emissions testing where I live. Sent from my SM-G950W using Tapatalk

I pulled the quote from a book. https://www.chapters.indigo.ca/en-ca/books/how-to-build-power-tune/9781845849597-item.html I've also heard a rule of thumb of running you stack to half the distance of your filter. Sent from my SM-G950W using Tapatalk

Nope. Stock springs for me. Going for 70s feel as much as I can.

I'm just posting this for anyone that searches in the future... The metal spacer with the adjustable yellow Koni insets from Z motorsports are installed flange side up. It wasn't clear initially, but that's how it all fits together with stock springs. Sent from my SM-G950W using Tapatalk

No label, but "KYB Made In Japan" was stamped into the bottom. Sent from my SM-G950W using Tapatalk

To help understand a bit more about the history of my S30 does anyone know when KYB inserts were baby blue? I've only ever know white or red KYB struts. Boy, were they ever wedged in. Thanks in advance. Sent from my SM-G950W using Tapatalk

Good tip. I'm going to do that this winter and swap out the cheap-o pump with a better unit. Sent from my SM-G950W using Tapatalk

@Zed Head@jonbill I idled on a steep hill without any problems and drove up 1 block long steep hills, again with no symptoms. Same 1/2 tank of gas. My next step will be a full tank and the longer hill that's caused me problems. Sent from my SM-G950W using Tapatalk
