Small Engines (Lawn Mowers, etc.): sears weed eater, weed eater, oil mixture

Question
I bought a sears 80 year anniversary weed eater about 2 years ago. ran strong until this last winter,when i put it away forgetting to drain the fuel/oil mixture. got it out this summer and it would not run,cleaned the carb with carb cleaner.tried to start it. still no luck,jumped the on and off switch with a paper clip. squirted starter fluid into the carb. and it ran for about 30 seconds, died again and not having any luck getting it to refire.what did I do wrong? I hope that i can be fixed.Help me please.

Answer
Did you refill the trimmer with brand new fuel/oil mix?  Did you disassemble the carburetor or just spray the outside of the carb with carb cleaner?

What the the trimmer model number?  The model number will be on a small sticker, about the size of a business card, and the model number format will be xxx.xxxxx.

Are you familar with priming an engine to get them started?

Let me know.
