Beth, I can almost accept the fact that the manufacturer didn't bother to update their materials to stay with the times.  But the unavailability of a simple retaining clip is not excusable.

GOOD customer service would have said, "It's not a replacement part, but If you'll send me a SASE I'll grab one off the assembly line and send it to you for free".

Same problem

I had the same problem with my old weedeater. My next one will be electric for sure. I had a battery operated one in the past, but it was before its time and didn't really even work. Maybe they make decent ones now.

I prefer the electric too.  They don't make as much noise and no noise at idle.  Best of all, they don't spit two stroke oil all over you.

Good points, Beth. This all leads me to believe I made the right decision with an electric weed eater. While the cord has to be dragged around, it is overall lighter than the gas-powered version. And, I don't have to worry about Ethanol.

Possible Epoxy solution to glue the bulb assembly back together

Loctite H 4710 or 3M DP 420 should be good choices to take the heat of a weed eater engine.

Thanks for the article, My weed eater just quit on me.  You have given me an additional avenue to explore

Beth,


The Federal Government has been promoting the use of ethanol in gasoline for the past 34+ years.

This was kicked-off by the The Energy Tax Act of 1978 which provided a $0.40/gal ethanol subsidy.

I find it hard to believe the same material has been used for the priming bulb for the last 34 years.

It is certainly plausible that a design change was made and old stock was not recalled.  A small mom-and-pop hardware store might have had this machine on the shelf for a while.

While there is certainly a disparity in the use of ethanol across the states (and in the counties within those states) I would still expect an ethanol-tolerant design.

As you say, I would also expect attention to evolving fuel standards and changes to keep materials in compliance.

This reminds me of my British sports cars from the1960s.  They used natural rubber, becuase the British with their empire were able to get it easily.  American cars typically used synthetic rubber parts.  These tended to last longer, and changes in the formulation of gasoline tended to impact unfavourably on the endurance of the British parts.  Of course, being foreign, they were more expensive.  We would replace them with American made rubber whenever we could find a match.

Would use of ethanol in this machine have been an after-the-fact development post its original design or should it have been designed that way from the get go? I'm asking because I'm assuming not much changes on a WeedEater machine, albeit a few bells and whistles here and there. That said, there such be some sort of regular revisting of requirements to keep up with new fuel standards. The other big question is likely where you bought the WeedEater. Perhaps some stores still have old inventory on their shelves that aren't retrofit to meet new requirements.

Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team 100 to make (about $161 US).
At Medical Design & Manufacturing Midwest, Joe Wascow told Design News how Optimal Design prototyped a machine that captures the wing-beat of a duck.
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
