I have one that i bought about 5 months ago. Took it camping snd worked flawlessly for the whole trip (about 4 days). Put it away for 2 mo. until our next trip. It once again worked flawlessly until the 2nd night. Out of nowhere it just shot off ftom running great. Started it up again but this time as soon as I start moving the lever to the run position the overload light came on and the unit turned off. Couldn't get it to stay on do i put it away. When i got home, I checked and cleaned the air filter, took apart the carburetor entirely, checked spark plug. All that work to no prevail. It still wont stay on on unles the lever is on the start position. Any help would be greatly appreciated. ..
