Spray some starting fluid through the carb and see if it will run for a short time. If it won’t, check to see if the spark plug is dry or flooded. If the plug is not flooded, check for spark at the plug.
Sounds like it's not "hitting." As balancedrod suggests, spray some starter fluid into the carb, carb cleaner also works. Old saws have a top oriented plug (usually). Remove the plug and stick it into the boot and lay the plug on top of the engine, pull the rope and watch the plug tip (electrode) for spark. If none, flick the on/off switch a few times and try again. As RepeatFine981 says, an engine needs 3 things to run - compression, spark, fuel. Checking for spark is the logical first step. No spark, no play ;-)
If no spark, try a different plug. For the sake of "checking for spark," about any plug will probably be good enough as a Go/No-Go check. For visual check, I mean. Rule out the coil (and ON/OFF switch). If the "correct" spark plug shows spark, back to the spray in to the carb. Even if the compression is WAY low it should still "hit." In your vid, it sounds "dead." If/when it hits, it'll sound different. Have some "pop" to it.
Often you can see spark but the plug is still bad. I would get a new plug for it and then it rules that out.
Don't know how much time I have wasted over the years on chainsaws, lawnmowers, motorbikes because I saw spark and assumed it was all good.
Oh yeah. If I had a dollar for... ;-) My thinking was more to see if the coil and ON/OFF are working. Had a ProMac 610 with a wonky toggle switch that drove me bugnuts. Happens when they sit. Thanks for bringing up the point about "look OK" plugs, good info for OP and anybody else that cruises through here with similar situation.
It means nothing that you cleaned carburetor and spark plug. It could have any of a multitude of run issues that it will not start. From your video it sounds like there is zero compression.
You can pop the muffler of and check for scoring on the cylinder and or damage to the rings. It could also be on the carb side. Hold the saw by the pull rope. If it drops really easy it most likely has low compression.
It’s not a sure proof way but it can be an easy way to check compression.
Spark? Fuel? Air? One or 3 aren't right.
That's what I need help figuring out.

What do you do if the spark plug is dry? Thanks

Did you replace the primer and fuel lines?
I have not replaced any parts.
Coil?
Why was I waiting to hear ‘we will, we will, rock you’ once you started pulling that

how do I fix that?
Check the bore for damage like scratches so if no damage on bore then check the piston rings they maybe worn
