Question about Husqvarna Garden
Try taken the spark plug out , using the starter cord slow pull on the string. Looking inside where the spark plug was, does the cylinder move up and down?
If it does you might have a bad ring around the cylinder.
One last thought, make sure that the spark plug is clean and re-gap correctly.

Four things I can think of:
1) There is a short in your spark plug wire. When you bend it to connect the plug in the machine it allows the exposed cable to contact the engine block. Examine the wire all the way to the coil.
2) Flywheel key is sheared ( you obviously know how to take off the flywheel since you checked the seals).
3) Flywheel air gap is not set correctly. Loosen the coil. Put the cover of a notebook or the cardboard piece of a cigarette pack between the magnetic portion of the flywheel and the coil. Tighten the coil down. This will get you the proper gap.
4) Your cylinder/piston or rings are scrubbed out. Even though it passed a compression test, on rare occasions it will loose compression only when it fires. So do the following:
Remove your exhaust manifold. Look into the cylinder with a flash light. You are looking for scratches. Anything larger then a light fingernail is definite proof you need a new cylinder/piston assy.
If it passes that test do the following:
Pour mixed fuel straight into your cylinder until 1/4 full. Slowly pull your saw over while looking into the cylinder. If you see bubbles after the ring/rings go by then you need a new cylinder/piston assy. On rare occasions if no scratches are present on the cylinder wall or piston, you may be able to change just the rings.
First if you can get a inline spark tester so you can see if your getting spark with the plug installed.

you say you cleaned the carb, most importantly, did you clean the jet in the carb. if not there your problem. The ethonal in gas will gum it up in a heartbeat if not run.
