I have the same issue with my blower as others. It will not even try to start. The head was not loose, but I pulled it apart to make sure nothing else was wrong. I didn't see anything out of the ordinary. No parts in the crank and it turned over fine. I couldn't tell if there was a ring in the piston. If there was, it seems to be solid to the piston. I put everything back, making sure seals were good and I get the same issue. Even if I spray starter fluid in through the carb. Not a hick up. Gas is getting in to the engine, the air filter is clean and the spark plug has spark. Is it possible it just isn't enough spark? Still seems like SOMETHING would have happened with the starter fluid. Maybe the piston ring has collapsed?
Sounds like old or stale fuel stuck the ring. This will reduce compression and prevent the unit from running. The only fix is to fix (unstick) or replace the ring.
I recommend using the pre-packaged fuels to prevent this type of problems.

Pull the spark plug after pushing the primer bulb and cranking a few times...if the plug is "wet" (indicating fuel is present in the cylinder) then the next step will be checking the compression...compression should read above 90psi (preferrably 100-125psi)...if compression is below 90psi, the most likely culprit will be a stuck piston ring.

its probably not getting any gas from the tank try putting your finger on the hole on the carberator and pull your finger should be wet if not take fuel line of the carburator and thenblow then take off the gas cap and blow through the hole on the gas tank it should flow freely throgh teh line to the carburator
Testimonial: "Thanks for the help. The gas line was dessolving on the inside and getting into the carb. I replaced the gas line."

also make sure you have 115lbs. compression min.....these models are notorious with head bolts becoming loose.

So far everything looks good. You're getting fuel, and you're getting spark. Only problem, is you've gotten too much fuel in it, and need to get rid of some before you can proceed. Take that spark plug out, and pull the starting rope hard several times. This will force the largest amounts of fuel out. Now's the part where you'll have to trust me. Use a match or a lighter to "flash" the cylinder. Make sure you don't have excess fuel spilled over the blower, but hold that match or lighter right up to the spark plug hole, and it'll "puff" at you. Please don't look into the hole while you're doing this. Flash the cylinder, and then pull the rope again, and flash it again. Next, make sure the spark plug is dry then put it back in. Set your choke to full choke, and pull until it hits once. Then put the choke on half, and it should start within 3 pulls.

Hello
Does it use a fuel and oil mixture?You probably did that.
Try removing the spark plug and cleaning it with a wire brush or some emery cloth.Make sure you have spark by connecting the plug wire and resting the plug on the metal motor block.
Do not hold the plug in your hand ,if you have no spark you may have a bad magneto.
