Echo PB-403T won't start

Last week it was my mower, now it's my blower that won't crank. I've cleaned the carb and put new gas in, but it still won't start. When I try to crank it, it sounds like it would if I were cranking with the kill switch on. I verified the kill switch is not on and it is the correct position to run, but that's what it sounds like. Anything specific I should look at?

From what you've said I would remove the spark plug and hook it back up to the spark plug wire. Make sure the tip or threads of the plug are touching the engine case and pull the cord. Do you see the spark plug sparking?

The plug is sparking. I did notice, however, when I pulled it out, it was extremely black. I rubbed it with my finger and it was like it had oil on it. Anything else I can do myself before I take it to the small engine shop?

Does it start with the air filter removed?

If you put a little gas into the plug hole, will it start?

Just so I don't blow myself up, can you define a 'little gas' when you say to put it in the plug hole?

Just a dribble, like a teaspoon or two full. It won't blow you up, just put it in the plug hole, screw the plug in , and see if it will start.

Put a little fuel in the plug hole, but it still wouldn't crank. Anything else?

When you pull the starter cord does it feel the way you think it should? It should get tough, then easy, then tough, then easy... Do you hear any strange noises inside the engine like loose pieces of metal clanging around?

Don't hear anything strange in it. It feels like it should start. It feels and sounds like I'm trying to crank it with the switch in the off position.

Try taking the muffler off and see if it will start, or if the exhaust port in the cylinder head is carboned up.

No dice. And that all looked clean also. This just doesn't make sense to me. I had this thing cranked and running maybe 2 months ago with no trouble at all.

I guess at this point, I would suspect it is flooded or the plug is just bad. If it has good compression, spark at the right time, and fuel/air mixture, it should fire up.

I'm gonna try a new plug this week. If that doesn't do it, then I guess it's off to the small engine shop.
