I think that the heart of the problem might be the bad valving. Have you checked pressure, and capacity?

We're back to 2000 deaths. And the WH is shutting down or minimizing the task force, apparently. This is the new normal. It's part of the background noise now. https://www.worldometers.info/coronavirus/

Here's an area where you might be able to actually have an impact. In your back yard. Get out the vote! Stir things up. https://www.spencerfernando.com/2019/12/18/while-trudeau-government-eliminates-canadian-coal-industry-federal-agency-invests-141-million-in-chinas-coal-industry-blacklocks/

Stop posting the pointless videos. See my edited response above your reply. Assembled in USA or all parts made in USA? Let's check that out.

But you'll still take the paycheck for traveling to China for work? Nothing you own was made in China? But, back to the original question, modified - what response are you expecting from your videos? The virus is here, no matter where it came from. How will knowing where it came from affect any of a person's actions? It won't change the hot spots. It won't change the need to wear a face covering. It won't change "stay at home" orders. It won't change any planning a person might be doing. Nothing will change "on the ground"' here in the US, or anywhere in the world.

You might try some experiments, moving the lever by hand, to see when in the stroke the pump actually moves fuel. There might be too much play at the beginning of the stroke. Could also be that the leaky valves inside allow too much fuel past on each stroke. If the problem is play, you could stack some gaskets to create a thinner spacer, to take up the play.

We're just having an absurdity contest... The truth is that the virus did come from animals, a bat-like humanoid. The flying monkeys in the Wizard of Oz were real, they were man's first attempt to create a flying human, experimenting on monkeys because their DNA is so close to humans. The bats that were used for the cross-breeding have escaped in the past, and now they've ended up in the Wuhan "wet" market. With proper nutrition certain COVID-19 patients will grow wings.

Here's an alternative conspiracy theory, that actually seems more plausible, to me anyway. Absorb all of the last three years in to your head and consider that maybe the virus IS man-made, but it was created in an American lab. Transported to China and released in a far away city there, with the goal of creating an epidemic, weakening China and bringing manufacturing back to America. Again. The Pompeo show is an effort to deflect attention away from the fact that the plan went awry and to provide cover in case some smart scientist discovers that it must be "man-made". Get ahead of the game. Much easier to believe that scenario, I think.

You should have watched some of Governor Cuomo's briefings early on. He often expressed amazement that everything that they needed was made in China. Ventilators, PPE, gloves...all of it. I worked for a large manufacturing company and almost all of our parts were made in Asia, many in China. I traveled to Asia and met a guy from Black and Decker doing the same thing I was - going to China to assist a contractor in making our products. All of our suppliers had plans in progress to build plants in China. And that was 12 years ago. 35 years ago people I knew in the tool and die industry were getting killed by "offhshore" tooling. It was cheaper to send your prints to Asia, have your tooling made, and have it shipped back than to have the local tool and die shop or in-house shop, make the tooling. For somebody who says that they travel to Asia a lot for work you don't seem to be accepting or understanding how the world of today works. We, the modern world's consumers, owe our luxurious life styles to the labor of the Asia population. China controls most of the world's manufacturing. None of the things that you suggested above will happen. "We" would have to give up too much. That's why nobody is paying any attention to Pompeo when he starts talking about the same thing. It doesn't matter, it really is a global economy and China is big part of the globe. If you really want to see something interesting, read these articles about Senator Mitch McConnell's wife, Secretary of Transportation Elaine Chao. They'll give you that queasy sick feeling. Now try to imagine how any of the things you suggested will possibly happen. https://www.politico.com/story/2018/05/06/elaine-chao-father-james-transportation-department-569686 https://www.salon.com/2019/06/12/mitch-mcconnell-and-elaine-chaos-empire-of-corruption-is-this-what-normal-looks-like-joe-biden/

Learn to enjoy the noises(s). As soon as you remove one you'll notice another. Coming up: diff howl, 3rd gear whine, rocker ticking, injector noise, mustache bar clunking.

Your cam is "bigger" than Jeff G 78's cam. The odds are against you. Jeff G knows his engines. Here's your cam specs. Racing Cam Stage III Intake 36-74 Exhaust 74-36 Valve Lift 0.490 Valve Lash Cold 0.010/.012 Advertised Duration 290 0.050 Duration 242 Here's Jeff G 78"s post. "I tried it - twice. The first time was circa 1997 with a L28 at 9.83:1 CR and a street cam. The engine was fresh and the car ran like crap. It had low power, wouldn't idle and was simply a disaster. Since the engine was new and the EFI a bit untested, I removed the cam and related components and returned the engine to a stock cam. It ran great and I was able to enjoy the car. The performance cam sat on a shelf for a decade or so. My Z was running great and was well-sorted, so I figured that I would try again. I installed the same cam and related parts back into the engine and got the same result. I tried to tune it, but it didn't make enough vacuum to keep the L-Jet happy. I once again pulled the cam springs and rockers and went back to stock. I then installed that cam into my SU carbed L28 racecar and it runs like a dream. It was everything I had hoped for in my street car. Both engines are very similar other than the fuel systems. You can try it, but many have the same results as me. L-Jet simply doesn't like low vacuum. For reference, my cam is a Web Racing Grind 91 with .450 lift and 260 duration"

You're avoiding the question - what will anyone do if it is found that the virus came from a China lab and is man-made? Describe an action that would be taken. Anything, keep it simple. One simple thing that will change if the virus came from a lab in Wuhan. No need for a video or three, just your words. Forward thinking, not backward. Something constructive, that might make things better.

The fuel pressure behavior is normal. 40 is higher than spec., which is 36.3. The mixture would be rich which might cause some problems. But the vacuum leak should have helped that. Why is "blipping the throttle" important? It looks like everything is working right. Here's the thread about big cams and EFI -

Here's another perspective, a scenario. China confesses that they were developing a virus, for potential use as a military weapon, it got loose and caused the pandemic. What changes in anyone's response? Nothing. China is huge and controls world manufacturing. What is anyone going to do?

If you have email notification then you saw what I deleted. China does not matter. Where the virus came from does not matter. If you had read the article I posted, or even jsut the excerpt, you'd see that it's a distraction. It's a bright shiny object, a red laser spot to a cat, it doesn't matter.

Is that from 2001 Space Odyssey? Just saw that the other night. Weird coincidence.

Seeking the sources for the stories about the source. Occam's Razor. Reduce to the essence. Then ask "why would this be true?". https://www.theguardian.com/world/2020/may/04/five-eyes-network-contradicts-theory-covid-19-leaked-from-lab Australia’s Daily Telegraph – a Sydney tabloid owned by Rupert Murdoch – has been focusing on the Wuhan lab for several days, culminating in a weekend report which cited a 15-page dossier compiled, it said, by “concerned Western governments” amid an investigation by British and other members of the Five Eyes intelligence agencies. Intelligence sources in Australia were quick to say they believed it was based on open source, public domain material. One told the Guardian they believed the information that appeared in the News Corp title was most likely to have originally come from the US: “My instinct is that it was a tool for building a counter-narrative and applying pressure to China. So it’s the intent behind it that’s most important. So possibly open source leads with a classification slapped on it.”

Never mind. We all have our obsessions. That's the point of the forum...

Can't really tell which line's you're talking about and if they are connected correctly. But the distributor's vacuum advance canister runs off of PORTED vacuum. In other words, it only gets vacuum when the throttle blade is off of idle. At idle it closes so that there is no vacuum, so no vacuum advance. The Nissan EFI system is known for "hating" big cams. There have been some comments about in just the last few days. If I find the thread I'll link it. The ECU and AFM are designed to run well with a certain set of engine parameters. Big cam isn't one of them.

I'm sure that the rubber in the factory bushings deflects enough to allow metal to metal contact. I found an image and pasted it as illustration. The only thing holding that little gap open is the modulus of the rubber. And that's not much. The PU bushings probably started as good "upgrades" for certain bushings, making things stiffer and less compliant. But many of the other applications just really aren't better than the factory bushings. Put an eyeball on that factory bushing with the thin rubber between two steel sleeves and compare it mentally to the replacement PU piece. I left my rear rubber in place, even though I had the PU as part of a kit. Just couldn't see a benefit.

The 280Z oil pan will fit fine in your 240Z. The 280ZX pan is different but it also will fit in a 240Z or 280Z. I think that fit problems happen if you try to put a 240Z/280Z pan in a 280ZX. Your biggest problem with an L28 in your 240Z might be the exhaust manifold. Not sure but think that the 240Z collector is a bit small and restrictive. Maybe not. Anyway, it should be a piece of cake.

The IHME has revised its analysis. Double the projected deaths. 134,475 by August 4. https://covid19.healthdata.org/united-states-of-america http://www.healthdata.org/covid/updates "What do all of these death model updates mean? Overall, these modeling improvements have resulted in considerably higher projections of cumulative COVID-19 deaths through August, primarily due to longer peaks and slower declines for locations that have passed their peaks. The magnitude of these effects vary by location, and uncertainty intervals still overlap considerably for many places. The mean cumulative projections shown in our online visualization tool and available for download are generally higher for currently included locations.

Here's a left of center view. Not as left as some, but probably not center https://www.theguardian.com/world/2020/apr/27/dont-judge-swedens-light-touch-on-covid-19-yet-says-minister

I don't think that this can be determined yet. Herd immunity is at about 80% apparently. Unless they've done enough testing to draw that inference they're not "done" with it. Unless you man almost all of the old people are dead. I don't want to get in to politics, but maybe you're not aware that the National Review is a super conservative magazine. You could probably call it "ultra" conservative. I used to read it about ten years ago when the spectrum from left to right was much narrower. Anyway, my point about that magazine is that they would be the views of the hard right. Everything's rosy, we need to start making money again. Inherently biased toward the "let them die" view. People are responsible for their own destiny, you're all on your own, get your own PPE, I've got mine. Ten years ago they seemed more rational. https://www.nationalreview.com/

Remove the breaker plate and look at the weights and springs. Sounds like the springs are gone or broken. Found a good video. You don't want to lock yours but he shows how to take one apart. 4 and 6 minutes show the critical parts.
