Small Engines (Lawn Mowers, etc.): Weed eater blues, air fuel ratio, aircleaner

Question
I have a 4 stroke Yardman weedeater, model YM26CS.  Today I was using it and all the sudden the motor died (fully warmed up).  I can only get it to run with the choke fully on, and when giving it throttle it will barely increase RPM's (with choke fully on).  If I start to move the choke lever (1/8 of an inch) to turn off the choke the motor immediately shuts off.  Do you have any ideas why this has happened?  I checked the aircleaner, and spark plug and it looks fine.  Plenty of fuel in the tank.  Any guidance on how I can fix this please let me know.  I have never had any problems with this before, the only maintenance I have done on it is change the oil once a year.

Thanks for your time, Travis

What seems to be the problem is that the engine is not getting enough fuel,because you have to choke it you are forcing the fuel by shutting off the air. When it starts it need air/fuel ratio be be correct. The carb needs cleaned or rebuilt,check any fuel filters make sure you are getting enough fuel to the carb,check the float and the needle valve and the needle seat.
