Good point Rob on electric weed eaters unless of course the government "mandates" a new 50 or 100hz standard. I'm sure they could come up with a good "reason" just as they came up with the ethanol scam that turns food into fuel! And it must be subsidized by all tax payers to boot!! (Notice meat prices skyrocketing?)
Also folks can still find "real gas" at pure-gas.org who list about 5000 stations nationwide. I'm remote but still can find it locally.
A couple months back some of our finest citizens broke into my place and took two Homelite chainsaws, along with lots of other stuff, that I have owned for years. I had not gotten around to fixing the enthanol damaged fuel lines so neither of them were operational. I hope they are having fun trying to sell these.
More and more products are really designed to be thrown away, why would anyone want to fixw them?
Sure is nice to have my small milling machine and lathe in the garage. Amazing number of small parts that can be produced in a short time to keep various things running long after the manufacturers expiration date has run out. And then I also have a Neway valve seat cutter so a 4 cycle engine rebuild is rather simple... How many folks even have a set of box-open end wrenches and a 3/8 drive socket set? Forget a good set of screw drivers.
The other part of the problem is that fewer and fewer people have any clue about how to fix stuff. Shop class is no longer taught in most schools and no-one at home has ever handled tools so we have a generation that doesn't know that things can be taken apart and fixed. (and then there are Apple products, when the battery fails you just junk it...) All the time spent with electronic gadgets doesn't really equate to many manual skills.
Ethanol didn't become mainstream as an additive until MTBE was outlawed perhaps a decade or so ago. MTBE was used as an additive to reduce pollution but was somehow making its way into ground water and became a public health concern. the government needed an alternative to the MTBE and thus began the ethanol 10% mix into our mainstream gasoline. In rural areas, gasoline can be bought without the 10% mix but it is 1) hard to find and 2) higher cost. The next time i go to Louisiana, I will bring a 5 gallon container and get some of the straight stuff.
Ethanol plays havoc in a different way too for small engines. Ethanol mixed in gasoline becomes unstable and gunk separates from it in as little as 14 days. Small engine repair place advised that we use ethanol stabilizer in our small gas cans whether for 2 or 4 stroke use. My girl friend's Honda lawn mower had its intake valve stick open due to this gunk. This caused a total loss of compression AND it would back fire throught the carborator. He pulled the valve cover and removed the valve and cleaned the gunk off of it. Upon reassembly, she was back to running. The repair guy suggested that after completing mowing that we pull the strating coard slowly until we feel the resistancebecome hard and STOP. Pointis to store the mower with both valves closed. If the valve is closed it won't get stuck open during storage. This is for a Honda engine that says "OHV" on it's valve cover.
That is a true statement also but it's going to be harder to change Washington than select the right material to deal with the problem. Unless we get at new president.
Connecticut recently switched from MTBE to ethonal fuel. I use the highest octane for my small engines, to help in starting and I add a product called seafoam that helps keep the fuel system in working order.
How about we demand the feds stop mandating the use of ethanol in our gasoline? Are we sheep? This was a bad idea from the get-go, it destroys fuel system parts and increases the cost of food. The energy used to produce the ethanol, after you factor in raising the corn, the pesticides needed, the hydration, etc. does not justify the savings in imported oil. A national energy policy that supported the exploration and drilling in and around the US is the way to go. Supply and demand is still a solid economic model, despite what the Riech and Krugman espouse. And let's get some new nukes licensed and construction started, while we are at it. And build that pipeline to get friendly Canadian oil to our refineries. And invest in using our abundent coal reserves instead of shutting down and refusing to license coal fired plants. And.... Well, you get the picture.
There is no excuse for not selecting the right material for carbs on these weedeaters. We have karted for years using alcohol for fuel and no material problems! Maybe some corrosion, but that is it. I blame the engineers for poor material selection.. shame on them!
I've had similar problems with my Weedeater, a chainsaw, and a small tiller.
So congratulations to me! and - thanks Mr. government genius for ethanol. I get to subsidize it on the front end, pay extra for food because of it, have my checkbook squeezed at the pump, reduce my gas mileage, and buy new yard equipment every couple years because of its deliterious effects. Is this a great idea or what?
Good point, TJ. That act of doing the simple, but basic things when it comes to customer service is definitely a lost art. On the other hand, I recently had a ceiling fan installed and the electrician who did it (ceiling are very, very high precluding my typically handy husband from taking on the project) commented that the fan motor was very loud and uneven when it ran in reverse mode to keep the heat circulating. The local store where I purchased the fan (I opted for local as opposed to the cheaper Internet sites) not only worked with their distributor to get me a replacement fan, they are paying the not insignificant fee to the electrician to reinstall the fan motor. That, without a lot of run around. I wish more companies practiced that lost art.
UK-based Plastic Logic and French company ISORG have created what the pair tout as a first in flexible printed electronics: a large area, conformable, organic image sensor printed on plastic.
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
