One of the features of the Wen units - can turn the operating dial nearly all the way off and it will run for roughly a minute until the residual fuel is gone. That combined with ~monthly operation has kept them in decent order.Don't forget to burn all the fuel off. 😁
Turbodog- Thanks for the link to that switch kit. I've been fortunate I guess, I exercise mine regularly but only drain the bowl once in a while. And thanks for digging around in there. BVH- I have to check my serial number today. My 7000 has been great except for needing a fuel filter at about 1000 hours if I recall. It started hunting and surging never shut off. These were a known issue and it's been fine since replacement.
There's no discrete detent on my Wen generators, simply a point between "fuel off" and "off" where you can feel the valve start to actuate hard shut. Stop rotation at that point and wait about a minute (no load, eco off).
Now that I look at it again, the valves are likely different. The Wen has a separate choke from the fuel on/off/hard off valve, unlike the Predator which combines the function.The next time i run my predator 2000 I'll try moving the switch to almost off and see if it dies after running out of fuel.
The Wen has a similar arrangement for full drainage of the fuel system.With the 3500, and I imagine the 2000 they have a hose at the bottom of the carb bowl that runs to a valve, and then another hose that runs to the bottom, and out of the unit. One can open the valve to drain the carb, or for that matter the entire gas tank. So they make that somewhat convenient, but you have to pull one of the side covers off and that requires removing three bolts. It would have been better if they were just pop on and off covers.
So when I turn the fuel off to my 10HP briggs and stratton snow blower and run it until it runs out of fuel, there is still fuel in the bowl?
Are you sure someone didn't have an alkaleak puke in there?This is why we clean float bowls, run them dry, and exercise equipment regularly. This showed up at a shop I used to work at, "It won't start, can you take a look at it." This is extreme obviously and took a long time but it gets the point across. Anyone who disassembles and cleans there own carbs should buy a cheap welding tip cleaner kit. Very stiff wire in various very small diameters, perfect for getting into carb passages.
