Honda ES6500 Generator – PLEASE HELP!

Leave a comment

By albertcamus

Hey there! Thank you so much for your help! I have a Honda ES6500 Generator – which has only about 20 hours on it, but has not been run in about 4 years… Prior to this, I serviced it every 9 months or so…

Anyway, per the manual – I have replaced the spark plugs, changed the oil, cleaned the sediment cap, changed out all fuel in the system and added Sea Foam – and have changed out coolant and checked, cleaned all connections…

Also, just put in a new battery…

(Just FYI – given the precise oil specs in the manual – I was sure to get both the oil and the plugs from Honda…)

It won’t fire… If I pour a LITTLE gas in the air filter, it will fire for a moment, but won’t stay on… Obviously I don’t want to do this too much, but just wanted to check to see if it would fire…

Given that the fuel can be drained out of the drain hose, and given that fuel poured into the carb with the air filter off – and will start and run for a second – I’m assuming I have fuel not making it all the way into the carb problem… I know my way around an engine enough to fix the problem – if I have a clear idea what the real problem is – but not enough to totally diagnose and go directly to the problem… Basically I know what a carb is and how it works, and know what jets are – but don’t know where they are specifically…

Anyway, I’d really appreciate help if anyone has any advice, or the actual service manual – I want to start taking off the carb and look for gump, but am not sure if this should be my primary attack…

Thank you so much for your help!

5 Favorite Sessions from Collaboration Summit Attendees

Leave a comment

By libbyclark

Now more than halfway through the Linux Foundation’s Collaboration Summit in San Francisco, attendees have started to weigh in on the best sessions and experiences so far. Some cited Monday’s keynote presentations from heavy hitters such as Samsung and Jaguar Land Rover. Others focused on the technical discussions in Tuesday’s sessions, which covered a range of topics from Automotive Grade Linux to kernel scheduler load balancing. And for some, simply meeting the developers on the other side of an email list provided the best experience at the conference.  

 

“It’s been great learning about the open source projects, in particular Jaguar and Samsung and the collaboration they’re looking for and that we can offer.

“Whether you work for a different company or not, it seems like you can really participate. I’m looking forward to some of the other technical presentations where I can learn about Linux and how it’s changing.” – Carol Sanders, Vyatta. 

 

 

 

 

 

“The subjects are great, but what’s even greater is getting to meet people and have discussions with people on the other side of engineering from different companies. I got to meet people I’ve been working with for several years but I’ve never met with them.

“Even some of the presentations we had that weren’t direclty related to what our company does triggered a lot of good ideas that I can bring back to the company and gave me some ideas for changes.

For cloud computing we talked about what’s missing and what can be done and especially from a storage perspective. We know we’re doing a lot on our end that’s really good but there are parts of the Linux kernel that need to be added as well.” – Abdel Sadek, NetApp.

 

 

 

“I was particularly interested in the Linux weather forecast by Jon Corbet yesterday. It presented some challenges that we’re going to face this coming year. Some of which I wasn’t aware, particularly in the new architectures with big.LITTLE and how that will imply changes in course scheduling code. Me working in performance issues, I find that attractive and challenging.

“I’ve been impressed with the keynotes and event organization as well. I hope tomorrow will be just as good.” – Davidlohr Bueso, Hewlett-Packard. 

 

 

 

 

 

“Today I attended ACPI 5.0 improvements, which is really interesting. I’ve been kind of watching the Linux mailing lists on Linux LKML. It gave me insight into balance bewtween ARM and ACPI and how we can use the same infrastructure to transparently implement.

“Also, being able to add GPIO interrupts and such, and see where I can contribute, possibly. The second one I heard about was power scheduling which was very insightful. There are a lot of questions to be answered in terms of getting it to primetime.

“And the big thing I’m getting out of this conference is

Jon Corbet Mulls Linux Kernel Changes

Leave a comment

By libbyclark

Collaboration Summit in April.” class=”caption” />

Now that the Linux kernel 3.9 merge window is closed, it’s safe to say we know what features will be included in the next kernel release. What lies beyond is predictable, still, but will likely hold a surprise or two. That’s where the annual Linux kernel weather report comes in.

Delivered by Linux kernel contributor and LWN.net co-founder Jon Corbet at Collaboration Summit in San Francisco April 15-17, the forecast will help prepare the Linux community for the year ahead.

In this Q&A, Corbet gives us a preview of his talk, reveals some kernel changes that surprised him last year, and discusses some of the biggest challenges kernel developers face in the months and years ahead.

What changes to the kernel over the past year have surprised you?

I do try not to be surprised by kernel changes – it’s my job to be on top of that stuff, after all 🙂

One of my biggest surprises, I guess, was when I realized that the Android developers had dropped their wakelock/suspend blocker implementation in favor of the solution that had been merged into the mainline kernel. A long-running, high-profile, bitter fight had been resolved quietly with almost nobody even noticing, and one of the biggest differences between the Android and mainline kernels is no more. A lot of credit is due to the developers in both the Android and mainline communities for their hard work in creating a solution that is acceptable to everybody involved.

Another surprise is the speed with which the bufferbloat problem has been brought under control. With a relatively small number of changes, many of the over-buffering problems in the Linux kernel were taken care of, to the point that the problem is pretty well solved for wired Ethernet networking. There is, of course, still a lot of work yet to be done, especially with wireless networking.

What features will we find in the 3.9 kernel?

We’ll get support for the ARC and Metag processor architectures. The “dm-crypt” subsystem enables the use of a fast (solid-state) drive as a front-end cache for slower storage. The ARM architecture now supports virtualization with KVM. User namespaces now work with almost all filesystems, making it possible to enable this feature in almost any kernel (though that may not yet be a wise thing to do).

What other new features are coming down the pike this year? 

Some of the more interesting work on the horizon may be the various solutions to the problem of scheduling on ARM big.LITTLE systems. The Linux scheduler was never written with asymmetric processors in mind, so it currently does not know how to schedule tasks to take advantage of the big.LITTLE architecture. The two existing patch sets try to solve this problem in very different ways; the “big LITTLE MP” work, in particular, will be the beginning of a new push to make the scheduler more power aware.

We will see the continuation of the ARM architecture cleanup work and, probably, true multiplatform ARM kernels for the first time. The integration of the Android code into the mainline will also continue.

What are some of the biggest issues kernel developers are tackling and how are they being addressed?

Is Qualcomm In or Out of Samsung's Galaxy S IV?

Leave a comment

By Evan Niu, CFA, The Motley Fool

Filed under:

Tomorrow’s the day for Samsung followers to get a peek at the latest and greatest out of South Korea. The conglomerate is hosting an event in New York to unveil its newest Galaxy S IV at 7 p.m., and will be streaming the event in Times Square. With the debut just a day away, it’s time for last-minute rumors to start showing up.

Are you in or out?
Bloomberg is reporting that Samsung is planning on using quad-core processors from Qualcomm as well as Exynos “octa-core” chips of its own designs.

There’s been much debate over what type of processor Samsung would use, since it was reportedly running into some problems with the Exynos 5 Octa related to power efficiency. Packing eight cores onto one chip comes at quite an energy cost, after all.

In and out
According to Bloomberg’s sources, the company will hedge its bets by using both chips. A Snapdragon will power the U.S. version of the Galaxy S IV, while an Exynos processor will be found in the international variants. Samsung has used this strategy before, including with its outgoing flagship Galaxy S III. From time to time, OEMs tailor devices to different geographical target markets.

For example, since the U.S. is the farthest along with the transition to 4G LTE, supporting LTE connectivity is critical for any high-end smartphone that has hopes of U.S. success. In most other parts of the world, 4G LTE networks are either inchoate or nonexistent. Many OEMs typically tap Qualcomm for Snapdragon processors with integrated LTE for U.S. models. HTC‘s 2012 flagship used a Snapdragon in the U.S. and an NVIDIA Tegra in the international version, as well. NVIDIA just announced its first integrated LTE chipset, the Tegra 4i, which may put some heat on Qualcomm in the smartphone ring.

Market it
Samsung will inevitably put a ton of marketing weight behind these octa-core processors, even though they function more like quad-core processors. The different cores are primarily to balance power and efficiency, but only four cores can be active at any given time. NVIDIA‘s Tegra 3 used a similar concept, using four high-power cores for heavy lifting and one low-power core for the easy stuff. Samsung’s implementation of ARM‘s big.LITTLE technology will instead involve using four low-power cores alongside four high-power cores.

But with Samsung’s recent marketing blitz, consumers can expect some headlines about “the world’s first octa-core smartphone,” or something along those lines, even if it’s a tad misleading.

Samsung has also been aggressively gunning for Apple over the past year with targeted ads. The company will likely come after the iPhone maker again, highlighting the fact that the iPhone 5’s A6 processor is a dual-core chip, while ignoring the fact that the cores inside are new custom designs with major performance gains. These cores are codenamed “Swift” and are comparable in performance to Qualcomm’s Krait cores.

The South Korean company will …read more

Samsung's Galaxy S IV Arrives Next Week: Here's What to Expect

Leave a comment

By Evan Niu, CFA, The Motley Fool

South Korean giant Samsung is set to unveil its latest and greatest smartphone, the Galaxy S IV, on Tuesday at an “Unpacked” event in New York. One of the ways Samsung has successfully replicated Apple‘s success in recent times is that there’s quite a buzz going around about what Samsung may have up its sleeve to follow up its successful Galaxy S III.

The company isn’t mincing words here, either. Make no mistake: the Galaxy S IV is being unveiled.

Samsung has had incredible success with its Galaxy S series of smartphones, announcing in January that it had reached 100 million in unit channel sales. The company was the largest smartphone vendor in the world in 2012 ,and the Galaxy S III was ranked the No. 3 smartphone worldwide in the fourth quarter behind the iPhone.

What can we expect on March 14?

Keep on biggering
Samsung has continued to push the envelope with device size and is one of the leaders of the phablet movement. Each generation of the Galaxy S has gotten successively bigger, and the S IV isn’t expected to break this trend.

*Rumored.

There’s been some debate over the display. Samsung is one of the biggest proponents of OLED displays, which has been greatly beneficial for OLED specialist Universal Display over the past few years, as Samsung’s unit shipments have soared. The company was reportedly facing some production challenges with manufacturing AMOLED displays at the full HD resolution it wanted, and as such it may have been considering a different display technology.

However, the most recent rumblings from SamMobile suggest that Samsung is going with a new type of AMOLED display that will be 25% more power-efficient. That’s incrementally beneficial for Universal Display, even if the company is still waiting on OLED TVs to ramp up.

All that and a bag of chips
On the processor front, Samsung had also been reportedly running into power issues with its Exynos 5 Octa processor and was thinking about sticking with a Qualcomm Snapdragon chip. The Exynos 5 Octa combines two different quad-core processors and is among the first implementations of ARM Holdings‘ big.LITTLE architecture, where high-performance cores sit alongside energy-efficient cores. In this case, Samsung is using four Cortex-A7 cores and four Cortex-A15 cores.

The Exynos 5 Octa technically has eight cores and as such will inevitably marketed as an eight-core processor, although this is slightly misleading, since only four cores can be active at any given time, depending on the task at hand. Qualcomm CEO …read more

President Clinton grabs the spotlight at Samsung’s CES Keynote

Leave a comment

LAS VEGAS—Former President Bill Clinton is the ultimate scene-stealer.

Samsung Digital Solutions President Stephen Woo talked new tech at the company’s keynote on Wednesday morning, but a new processing chip and flexible display prototypes didn’t make people leap to their feet the way Clinton’s on-stage appearance did.

“When I became president, the average cell phone weighed 5 pounds,” Clinton joked in an off-the-cuff speech that tackled gun control, climate change, and the ways technology can topple governments and boost developing economies.

Clinton capped an event that included the debut of a new chip, the eight-core Exynos 5 Octa, based on ARM’s big.LITTLE processing technology. Woo demonstrated the chip’s superfast speeds by downloading an app to make reservations at Las Vegas restaurant Honey Salt while mapping the eatery’s address. He also invited Electronic Arts’ Glenn Roland on stage to demonstrate the chip’s powerful game-playing experience.
