I've had this blower for going on 6 years. Always ran like a top. A couple months ago it started running poorly, hard to start. I thought my bad for leaving fuel in it over the winter so new plug, fuel filter, air filter and muffler gaskets. Exhaust screen was clean. Picked up a can of pre-mix fuel. Still didn't run like new and still hard to start, so put on a new carb. Now it won't start at all. I get spark, compression is good, but doesn't seem to be a wet plug when I pull it after 15-20 pulls. I'm sure I have the fuel lines right - it won't purge one way and the other will. I don't get any kind of notion its trying to start (yes, the switch is on) and I've fiddled with different settings of choke and throttle. Anything else to try, I'm frazzled?

Try starter fluid to see if it kicks at all. Another plug?
Along with trying another spark plug.
Did you make the "initial adjustment" on the new carburetor?
1. With the engine off, turn HI speed screw, (the small top screw on the carburetor closest to the rear of the machine) counterclockwise till it stops.
2. Turn the LOW speed screw, (the small top screw on the carburetor closest to the front of the machine) midway between stops, (extreme clockwise and extreme counterclockwise).
See if that makes any changes.........

Sounds more like an ignition issue since the spark plug comes out wet. You say you have spark but, is it a nice yellow spark that arcs to ground about 3/8 + inches?
Another vote for spark plug issues.

That plug should be soaked after 15-20 pulls!!! Recheck the fuel lines for cracks, correct locations, cracks, filter in bottom of tank.

Thanks for the tips. I'll give her another go this weekend.
Remove the plug, pour a teaspoon or less of actual fuel mixture into the cylinder, replace plug, and attempt to start.
After a few pulls, it should fire on the fuel that you poured in. I have done this a few times on stubborn equipment and for one reason or another, it gets fuel pulled into the carb and then it begins running. Maybe something clogged in the carb gets dislodged??
At least this will tell you if it is indeed not getting fuel to the cylinder.
Did you install the carb correctly with the gasket aligned correctly and tightened down well so it doesn't suck air?
Like above, check all fuel lines from inside the tank up to the carb. You already said it's getting a bright spark.
