No it's AVR issue. Check the field coil connections first. See if the coil's connections are not broken. if that's okay then check the voltage on AVR input terminals.

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!

Make sure there are no vacuum leaks on the engine manifold side of carburetor. There are 3 o 4 pieces on the engine side so inspect well.

If no leaks on engine manifold side then likely there's a blockage somewhere in the carburetor high speed circuit. Most economical solution is chinese knock-off for ~$20 US delivered.

If you can't find a cheap replacement then you'll need to do a deeper clean of carburetor by removing welch plugs and submerge in carb cleaner. You will need new welch plugs (kit) and likely kit will cost more than a knock-off carb.

Before tearing down carb, you could try Seafoam fuel treatment... probably less the 50:50 chance it will clear.

There are many ways to start. First, the starter is weak, and the second is that the starter does not move. If the latter, check the controller for signal output. If there is no signal output, check the battery for voltage? If there is pressure, the controller may be broken.

Take the carburetor apart and clean it. Then put a new correctly gapped spark plug in it. You should not need to use starter fluid.

I don't know your equipment, but the unbalanced term may refer to too large a load connected to one leg of your split phase service. Go to your load panels and try to get the amps drawn by your loads to be more equal. You may be over taxing one leg and have available capacity on the other, assuming you are running a 110/220 V split phase output.
