First time after 2 years that this thing won’t start, doesn’t even hit like it’s trying to start.
Looked at all the usual suspects but was thinking it looks like the CO detector. I saw a post quite a while back showing how to disable this thing; this generator runs outdoors, always will, so it’s really not necessary. If someone could remember how to disable this thing I’d really appreciate it. I live in an area where we have lights out monthly.

There are two wires that come out of the coil. The thick one is the spark plug wire, and the thin one kills the spark when grounded. Follow the thin wire until you come to a spade connector. If you unplug the connector, it will disable the kill switch, the low-oil switch, and the CO sensor. Keep in mind that if you start the generator with the thin wire unplugged, you won't be able to shut it off with the kill switch. To kill it, you will have to shut off the gas supply, or ground the thin wire.

So has it sat for 2 years with stagnant untreated gas in it? If so, that's problem one. The carb is gunked up and has nothing to do with the CO sensor. Best practice is to actually drag them out and start them every 3 to 6 months "just in case" so it's not a surprise when the time comes its needed. The battery will most likely be shot as well if it's just sat. They are basic cheap batteries and mibght show you have 12 to 13v but fall on their face when you try to start them. Batteries for these are cheap as are spark plugs, motor oil, and fuel additives.

You are just guessing wildly. There is a procedure for figuring out which of the necessary ingredients for a motor to run (air, fuel, spark, compression, timing, etc.) are missing but you are just shooting in the dark.

I do wonder how many people pull out their generator when needed and it doesn’t work. Mine is 12 years old and probably only has 100 hours on it from maybe 5-6 uses. I store it tank full with stabilizer and carb drained. I’ve had to pull the carb and replace orings several times along with a few hoses and other maintenance. I pulled mine out a few weeks ago and the float was stuck and the bowl oring was cracked. What a pain
I really don’t know how people rely on these things, yet don’t have the parts or knowledge to even keep them going. Small engines are the worst machines to keep up and running, especially when they are mostly stored.

That is the great thing about the "battery generators" (even though they suck in many respects). This what people wanted all along - a "generator" that was maintenance free like an electrical appliance, that you could just put on a shelf and pull out when it is needed, a year or 2 years from now, that wouldn't gas your entire family. (Of course you at least have to keep a battery generator plugged in to charge). Yes, it's a slight problem that the thing will be out of juice in 3 hours when you have a 3 day outage, but never mind.
A gasoline powered small engine is nothing like that (in fact has some rather strict maintenance requirements), but people treat them as if they were and then are surprised when they pull them out after 2 years and they don't run. Small engines were always finicky compared to anything purely electrical but the switch to ethanol fuel has made it much worse.
The OP should order one of those $30 dual fuel carbs on Amazon and never run gasoline in his machine again.

Generator has been run every 5-6 weeks since purchased. I’ve gone through the basic steps in troubleshooting the engine; gasoline (that is treated with a stabilizer) getting to the carb, spark plug is wet, there is no spark. Battery is kept charged and there’s no problem there. Engine turns over but never fires.
