It's odd how you keep overlooking the fact that staying within the capacity of the healthcare system saves lives. You should watch Governor Cuomo's morning briefings. He understands this and explains it very well, and is planning re-opening based on that principle. He has an actual long-term plan. A healthcare system that is at full capacity cannot care for any new patients, no matter what their problem. Car crashes, overdoes, assaults, etc. all get left outside because the system is full. The main point of flattening the curve is to have some capacity left for the rest of the patients. The alternative is to reject all of the COVID-19 patients because it's an inconvenience. Aside from the moral aspects, doctors have taken an oath, the Hippocratic oath, to take care of all patients. I can't really imagine a society where we're out and about, spreading disease, because we want to go see a movie or workout in the gym. I understand the economic reasons, working to produce the things we need to live, and things that can be produced at low risk. But trading lives for personal enjoyment is unimaginable. I guess it boils down the definition of harm and good.

Can't remember for sure but I think that they are studs attached inside the firewall. I would lube them up with penetrant and be careful when loosening. I broke one loose from the firewall on either the brake master or clutch master and had to do some tricks to get it off and get it bolted back together. Not sure that you can reach it from the back. I might be wrong though. Maybe it's nuts attached to the firewall.

One of the threads in that search I linked has a picture of where to take the 92mm measurement. It's from the flywheel surface to the ears that the fork rides on. Set the sleeve on the pressure plate and measure. 92mm is not exact but if you get it it should work fine. It's kind of a "can't go wrong" number that many people have confirmed.

You'd be surprised at how much air can get through that small gap around your throttle valve. I think you need to adjust those so that they're fully closed.

Make sure to confirm the height of your pressure plate and throwout sleeve stack. It's a big deal if it's wrong. https://www.classiczcars.com/search/?q=92mm

That's what the butterflies are for (throttle valves). Something isn't fitting here. If the butterflies are "closed" then the microfiber should have no effect. Got a camera? Take a picture of a closed butterfly valve. p.s. the SU concept is unusual. The pistons only respond to engine vacuum. There is no control mechanism for them except vacuum. the throttle valve controls air flow, the pistons just respond to engine vacuum.

Check the simple things like making sure the throttle blades open all the way. You never know.

How do you "starve the carbs" if the butterflies are already closed? Doesn't make sense. Unless a passage was left open that bypasses the butterflies. Sounding like an error in the rebuild.

There's only a bell curve if we stay "closed". "Opening" will change the curve.

A funny story that leads to a guy whose Tweets are worth reading, I think. The Australia view. https://www.theguardian.com/world/2020/apr/27/australian-nobel-prize-winning-immunologist-accidentally-twitter-drink-dan-murphys https://twitter.com/ProfPCDoherty

Download the Owners Manual, it has a nice diagram on the last few pages. Might help. https://www.classiczcars.com/files/category/17-owner-manuals/ Or maybe this picture will have enough detail, it's copy of the page.

You could probably find a low miles Sportage in a wrecking yard. The seals peel off easily and can be reused. Probably cost $30.

You said that your higher RPM would be a problem. Mazda has it covered, and has high output alternators.

This is surprising. The UK has a terrible death per capita ratio, along with France, considering that they are both "developed" countries with health care that is essentially socialized. The USA is at 167 today, but, of course, we're still early. Makes you wonder what the point of advanced "civilization" is.

Another "not a video" but I felt the need to share this. It might actually be relevant for some people. 5 second rule does not apply, I assume. https://www.healio.com/orthopedics/curbside-consultation/{5bc00bef-9d1a-4d21-80e3-f991436c361a}/what-do-you-do-if-you-dr

Here's another tracker. They have a Twitter thing also. It was put together by reporters and seems to have that"right now" style to it. Makes good "news" but not as useful as watching trends. Dramatic statements about what "just happened", followed by disclaimers. https://covidtracking.com/ https://twitter.com/COVID19Tracking?ref_src=twsrc^tfw|twcamp^tweetembed|twterm^1254519919925837824&ref_url=https%3A%2F%2Fwww.theguardian.com%2Fworld%2Flive%2F2020%2Fapr%2F26%2Fcoronavirus-us-latest-news-trump-birx-cuomo-updates

If these were mine and I knew how to make a Weber run richer I'd just go straight to that. Most carbs you'd just raise the main jet needle and it would get richer everywhere. Do that and if it gets more power you'll have a clue. It will probably stink like gas at cruise but you'll know how to solve the problem. There is a bunch of Weber stuff out there - https://www.racetep.com/manufacturer/carbs-and-injection/weber/weber-carb-tuning-and-technical-info/jetting-and-tuning-downdraft-and-sidedraft-weber-carbs.html p.s. pretty sure that the L26 engine has at least as much power as the L24. That was the whole point of increasing the displacement. I would avoid mechanics who make blanket statements like that guy above did. They usually don't know what they're talking about. And, you might have been just talking to some kid at the parts counter. Who knows. Edit 2 - and they, the 240Z and 260Z, had the same 0-60 times, 8.0 seconds. Since they didn't come with Webers it might just be that a PO's efforts to make more power had the opposite effect. Not uncommon.

People in a hurry... A Louisiana pastor held services at his church today in defiance of house arrest orders following an assault charge stemming from his decision to hold mass gatherings that flouted public health orders. The Associated Press reports:

Here's another good use of the Johns Hopkins data. The graphic is not so dramatic as others, easier to get a feel for what's happening. It would be good if somebody could use this form of illustration and animate it, showing growth and spread from the beginning. https://www.npr.org/sections/health-shots/2020/03/16/816707182/map-tracking-the-spread-of-the-coronavirus-in-the-u-s

This web site also has some good analysis and explanation. Here is today's. The US is stuck at about 2,000 deaths per day. 54,247 total as of now. "Opening up" is not going to cause the numbers to drop. https://www.mdmetrix.com/covid-19-projections Update for April 25, 2020 New York remains the only state with data signals indicating a stable descent path for reported daily deaths from COVID-19 (now at 15 days).The U.S. as a whole has left its exponential growth phase but has remained in a 20-day plateau phase. We’ll continue to monitor for data signals that would indicate a transition for the US onto a descent path.Encouragingly, there are now 15 states (California, Florida, Indiana, Illinois, Kansas, Louisiana, Michigan, Missouri, New Jersey, Massachusetts, Mississippi, Ohio, Tennessee, Washington, and Wisconsin) with overlapping data signals indicating they have left their exponential growth phase. We’ll continue to update the death curve charts, and will monitor whether these states show signals of improving further (entering a descent phase) or deteriorate (resuming an exponential growth phase). —Dr. Dan Low, Chief Medical Officer of MDmetrix

I don't know the mechanical pumps well. Airtex makes some good products. Carter has been around for a while. The carb'ed guys would know better. If you go electric then you need to think about safety shutoffs and proper pressure regulation, and wiring and other odds and ends. It's simple in concept but takes some work. There are threads on the site about problems trying to go electric. There's always something... Or, and if you can't return that pump it might be worth a shot, maybe adjust the arm. You seem to think that it works if it gets proper stroke. Maybe the first part of the stroke is dead and if you get the arm closer to the eccentric it will work.

I bumped up my idle RPM by about 100 and it made a difference. Might get you an extra 1/2 volt at idle.

Seems like you have it narrowed down pretty well. A bad aftermarket product is not uncommon. You could just return it and get a different brand. Delphi looks like a run of the mil auto parts store brand. No offense. https://www.rockauto.com/en/catalog/nissan,1972,240z,2.4l+l6,1209169,fuel+&+air,fuel+pump,6256

Since the car is new to you and might have had many previous owners I would give everything a thorough look to define what exactly you have and how it is set up. Might not even be an L26, it could be an L24. Check the stamping and castings on the block and head. Might have the wrong heads on it, we've seen people create low compression engines by using the wrong heads just to get an engine running so they could sell the car. Could be that the cam timing is off, that would have a big effect. Clogged exhaust, smashed exhaust pipes, who knows. Plus, you said you measured "compression" and checked timing, but did not give nay numbers. The numbers are important. Also, "timing' is usually just the initial timing. But does the advance mechanism work? You might be running 7 degrees advance at 4000 RPM. You can check that with a timing light. And you didn't mention checking or adjusting valve lash. That is the very first item in the Tuneup chapter. Very important. Just some thoughts. Make a list and start filling it up with numbers and observations, and post them here. No offense, but you really have not done a lot, there's a bunch more that will help. That's good news, there's hope. Plus it's fun.

This is the bothersome part. I'm not an SU guy. But the float bowls should not be siphoning empty with the filter's emptying.
