So back ground.. I bought a sportsman GEN7000 genny last summer.
Prepped per directions, run with gas in summer and late Fall for about 30 min each time with gas and stabil. Each time was put away by turning fuel off letting carb run dry and siphoning out old gas. ( gas never sat in it for more than a day)
Last week Electrician put in a transfer panel, we hooked up the genny to it to ensure proper connection etc etc..
The genny was outside all day in about 4 degree weather.
It started fine (not connected to the transfer panel) with choke closed, then ran for another 30 seconds and choke slowly opened. Even after 30 min i couldnt open choke all the way, it only went to open 70% before the genny rhytmically surged but never turned off. Yuo could see the governor working back and forth in rhythym with the engine surging
We connected to the panel with the choke open and the genny surging and it outputted steady 240 volts but you could see lights in the house dim in rhythym with the genny surging noise. I cant remember if the light s dimmed steadily or output was steady with the choke only open 70% and no steady rhythmic surging.
I figured the carb just got clogged with fuel and was ready to tear it apart. but reading the manual it said that the air and gas flow ratio needs to be reset if the genny doesnt run. Turn the screw till it bottoms out then turn it out 2 1/2 turns out.
So today I went out in 12 degrees, genny turns on easily, ( again NO LOAD) and open choke to 70% before i see the same surging symptoms. I bottom the screw out and the surging dissapears and I open the choke full open. I start to turn the screw out 2 1/2 turns out but the surging returns after only a 1/4 turn out.
What gives? Should I turn the screw out under load only? (I didnt do that today as family was over, it was prohibitive) And more for just my knowledge why did it run fine in summer and fall but now now? Colder/ denser air? ethanol in gas? Tomorrow I'll run it with choke 70% open just before it surges. Then hook it up to the transfer pan and get a load on it and open choke all the way and ill hear the surging. Then Ill play around with that screw and i'm assuming i'll hit the magical screw turn.. right?
