Small Engines (Lawn Mowers, etc.): Troy Bilt 4-cycle Gas Trimmer, air mixture, gas trimmer

Question
I have a Troybilt 4-cycle gas trimmer model#TB475ss about 2yrs old. It starts up fine and idles good ,but stalls out when I try to accelerate. It has fresh gas, new sparkplug, and I have cleaned air filter and spark arrester. Any ideas on how to fix it?

Answer
 Hello Roger:

 Turn the Low Air Mixture Screw Counter Clockwise 1/4 Turn. If this Doesnt Help, then Clean and Rebuild the Carburator. Hope this Helps. Let me know what Happens, Please. I enjoy knowing the Outcome. Thanks.

 Good Luck

 Respectfully

 John
