OK, I remember this discussion from the past. I guess it would be good to know if you actually had the engine running after you had the head/exhaust cover off. You say the plugs appear wet, please be sure they are not wet with water. If the compression is OK, try pumping a little fuel oil mix into each cylinder.
You can fish the starter rope around the pulley an extra time or two without disassembly to tighten up spring tension if needed, trying to start that engine with the rope wrapped around the flywheel will be a struggle!
No need to pull the flywheel if the spark will jump a 1/4" gap, just be sure the leads are on the right plugs!
