If the spark plug is wet with gas it usually means you are not getting a spark of it was flooded.
Remove the plug. Attach the plug to the plug wire. Lay the plug against the engine block so you or a helper can see the electrode. Hold the plug securely in place with something non-conductive i.e. rubber handle pliers, a piece of wood, screw driver, etc
Pull the starter rope and check for fire.
If no fire, the plug could have an internal short or the on/off switch may be faulty or possibly a broken wire

Check the cylinder bolts. They often come loose on those blower engines.

There are a lot of things it could be. The exhaust could be clogged (but one wil usually start and run at idle with the exhaust plugged unless it is completely stopped up). It could be a seal that blew out at the crankshaft, or any air leak into the crankcase.

How does the engine "feel" when you pull the rope firmly but a little slower than usual? Does it have a sharp definite compression stroke? Your descriptions also fit with low compression, and your compression reading could be about borderline...but there are a lot of things that can affect the compression reading on such a small chanmber, so it might not be that accurate of a reading. I go by the feel more than anything when dealing with small 2-strokes. Try adding a bit of straight two-stroke oil to the cylinder through the spark plug hole, and then try it again. If it starts up, the ring and/or cylinder is stuck or shot.
