How do I fix my Poulon Pro Trimmer?
 
                At 1st the engine wouldn't start, then I cleaned out the carbuerator, filter, new spark plug. The engine starts on choke, but when I take it off choke it revs then shuts off.  I tried adjusting the screw on the side of the carb; that didn't work. There could be a leak coming through the carb. How do I fix?
