Generarc RS 5500- Need help !!!!

I am looking for help in getting my Generac RS 5500 running. It only has about 6 hours on the machine. Last week I started to get ready for Hurricane Milton and attempted to start the generator.

• I attempted to start the generator, but the pull cord appeared locked, and I was unable to budge it.
• I removed the cover and turned the flywheel nut with a socket, and it all was well.
•  I then attempted to pull start the generator and the generator just wouldn’t start. It didn’t give any indication of wanting to start,

• I checked the gas tank, and it had minimal fuel.
• The fuel smelled bad
• I emptied the tank and drained the carb. I eventually put in non-ethanol fuel.
• I removed the carb and took it apart.
• There was fuel which was gummed up and in the main jet and the extrusion tube.
• I thoroughly cleaned the jets, tube, and all orifices of the carb.
• I cleaned all holes in the jets, tube, fuel drain bolt, and all other areas.
• I changed the spark plug.
• I tested for spark by grounding the plug on the metal of engine and did receive very good spark.

• I put everything back together and it still wouldn’t start. It didn’t even attempt to turn over.
• I disconnected the low oil wire and attempted to start the generator, and still nothing.

 
I have very limited knowledge of working on gas engines. I was wondering if there is anything else I could look at. Is there something I overlooked?
Just as a reference, there is no power switch and only a fuel vent dial. The fuel is getting into the carb bowl, so it’s flowing.  
 
Any help would be appreciated!!!

I am sorry, I forgot to mention, I used carb cleaner in the carb and still nothing. I even tried carb cleaner down the spark plug passage.
 
It just doesn't even attempt to start, and I have tested for spark. Could it be something, because I spinned the flywheel and knocked it out of time?

I am familiar with the terms, but have no experience with doing it. Do you know of a video or reference where I can get familiar with what I am looking at?

Check compression.  
 
With it sitting and locking up, the rings may be froze up/damaged.

If it was the carb though it should temporarily start with starting/carb fluid into carb or thru spark plug hole. Probably some long wait times at small engine shops with Helene and Milton damages.
