you probably have either a bad capacitor or more likely a short stator winding due to previous overloading

Verify that the double gang circuit breaker is good on both sides. Check for loose wire on breaker or receptacle.

To have success using starter fluid as a diagnostic you will need to remove the air filter cover and element. Then with choke open make a short (1 second) burst of starter fluid directly into the carburetor throat. (There is no need to saturate the intake with starter fluid... it is bad practice.) Promptly pull starter cord no more than 3 times. If you have compression and proper spark, it will fire and run for 1-3 seconds and stop as it will have expended the available fuel (starter fluid).

If it doesn't fire, repeat procedure. If still doesn't fire, likely no spark or plug is fouled. Promptly remove spark plug and check that plug is dry. Then check it has proper gap and you have spark. A wet plug will imply it is flooded and a flooded engine will not fire even with starter fluid.

If it does fire, then the likely problem is no fuel or water in fuel. Drain fuel bowl and some fuel (1/2 pint) from tank (just open fuel shutoff valve with carb bowl drain open) into a clear glass jar, let set for a minute and check for visible water line. If water visible, drain tank and refill with fresh fuel (use a clean EMPTY fuel container go to filling station and get 2 gal. fresh). If no water, then likely carburetor is fouled and will need service.

If it's on a Ryobi Generator then it should be a real Honda Engine. It's possible that it's a knock off or was replaced with one. If you bought it new from a reputable source then it's real, if it's used or came from an offshore source for a really low price then it's a good possibility that it's a kkoxk off. In all honesty, from my experience they do a great job with the knock off engines & they're usually reliable and last a normal life span similar to a real name brand.

Either way, that mechanical Issue Remains, I'm assuming you're refering to the valve being stuck and basically keeping the engine locked up and not allowing it to the over when attempting to start it. Sounds likely. Did you take the spark plug out and turn it over to see if it'll turn over at all to ensure it's not just totally locked up? My suggestion would be to Remove the valve cover and spark plug so that you can see the valvetrain in action when(if so) it is turning over and observe it to see if your valve theory is correct!

Thanks and good luck my friend, see the infinity below please, have a great day!

The reduced atmospheric pressure at high altitude means the standard carburettor settings will not allow sufficient fuel to flow for efficient running.
The dealer or manufacturer should be able to provide details of alternative settings - the jet sizes are usually increased a few points for every 5000 ft above sea level.
The cooler temperatures experienced at high altitude would probably change the engine oil specification to a lighter or thinner grade.

The Honda 5.0 gc160 owners manual calls for an NGK BPR6ES for proper heat range. Should be available at any Lawnmower shop or online at ebay

I would suspect that the inverter is fine and would look towards carburetion. The inverter, in addition to supplying the correct voltage and current, monitors the current being drawn by your connected load. It controls that stepper motor on the top of the carburetor and increases the throttle to increase the engine power to support the load. (Mechanical power in = electrical power out.)
Start the generator and then add a small load to the outlet, 100 watt light bulb or something. I use a space heater that I can turn on just the fan. See if it still stays running. Then increase the load (with my heater I go from fan only to the first level heat 1000w) and watch the top of the carburetor to see if the inverter increases the throttle to compensate for the increased load. By the sounds of what you are describing, it will go to full throttle and the engine will die because of a restriction on the available fuel. If that is the case, take the carb off and clean it. Or if you are not the carburetor rebuilding type, buy a new one.. they are only about $80. Not a bad fix for a $2000 generator :)

Likely a valve stuck open. Pop the head off and verify. If so, try to free it by spraying a a light oil around the valve stem and possibly rotating the valve to free it. If you damaged the head gasket removing the head, it will have to be replaced. Be careful to torque the headbolts symmetrically so as not to crack the head. There will be a troque spec but I do not know what that is.

It depends on if its over voltage or undervoltage. I would check the governor linkage and throttle settings while using a volt meter and a 100W incandescent bulb.

i thought id answered this, if there is an eye glass check the oil level mate, its normally below one of the handles, sometimes you can screw the eye glass off and top up

Check the oil level, low oil will stop the engine from continued running
