Wonder how one would last compared to a Honda? I have 3 EU2000i generators that are worn out. Each one has over 20,000 hours. I put hour meters on them before they are ever started the first time. If they were cars that equates to over 1 million miles each! I just ordered new rings for one of them to see if that will help. If it does great if not no big loss I got my money's worth as far as I am concerned... At this point in time I could really use a EU3000i.

I'm not aware of it having a fuel pump, so that means it's gravity feed from the internal tank only. Not a problem in my intended use as I'd get the 6 or so hours on a tank at half load and then let it cool to refill. I plan to use it to charge the battery bank when there isn't enough sun, so not being able to have an external tank and run "forever" isn't of major importance. I'd guess that it's not designed for 20,000 hours but, in my use, 2000 hours at 6 hours/day = 333 days. If we average 2 days/week of clouds/rain/snow that's 12 hours/week = 624 hours/year; 2000/624 = 3.2 years. If the engine lasts 5000 hours, then it's 8 years. 10,000 hours gives 16 years.
At my age, it's not likely I'll be pull-starting the gen in 8 years...

I bet it has a fuel pump due to the design. The carb sits at about the same height as the top of the tank if it's made like Honda's are, which I bet it is.

No fuel pump. I've had this one apart because it would NOT start when I unboxed it. On opening it up, I found the mount on the carb for the stepper motor that controls engine speed was damaged (carb is about mid point vertically on the engine. so below the fuel tank so gravity feed). No marks on the gen's plastic case but I did find what looked like a forklift fork puncture on the box the gen was shipped in. None of the online parts houses showed having the carb in stock so I emailed customer service at each place. I got ONE reply, that they had ONE in stock which wasn't enough to list online - and a name and phone number. I called. The carb was $50 delivered so I gave a credit card number and had that carb in hand in less than a week. I also filed a shipping damage claim with FedEx. Because the seller of the gen had NOT included the total price on the shipping invoice, FedEx refunded the shipping cost and paid their standard $100 in damages. I was OK with that as it covered the replacement carb and I have the extra $$ to buy a marine gas tank to have 24 hour run time. Meanwhile, I've found marine gas tanks on the Free section of Craig's List - I'm just waiting for one to turn up that's closer than the 100 mile roundtrip to the lake.
You do need three hands to reassemble the clamshell case, as the gas tank sits in molded-in notches and you can't see what you're doing when putting it back together. The new carb runs fine. I only lost a teaspoon of gas in the process of swapping the carbs and I probably know more about that gen than 99% of its owners.

Good to know. All of this style I've seen use a pump like the Honda's do. Thanks!

I didn't see a fuel pump on my gen, but my gen is a few years older and that could have changed.
Maybe if they posted interior pictures so you would know what you are/aren't getting?

Found this earlier Papa and thought you might be interested. www.nooutage.com/hydroele.htmIt tells you how much power a given amount of water and fall can make. |

Thank you. That's likely where I did the calculations for one story because it's not simple math. I have the formulas but "fill in the blanks" is easier ;-) Their focus is water turbines, not waterwheels but similar concepts, with waterwheels being less efficient than turbines but easier to build.
