Small Engines (Lawn Mowers, etc.): Poulan/Weed Eater Gas Trimmer model #GTI19T, weed eater gas trimmer, air mixture

Question
I have changed all fuel lines, the fuel filter, and air filter.  The engine will start and run for a short period of time, and then shuts off.  I cannot keep it running.  I also cannot find a manual for carburetor adjustments.  Can You provide any assistance?

Answer
Hello Steven:

Remove the Muffler and Ensure the Exhaust Port, Muffler and Spark Arrestor Screen are Not Blocked with Carbon. Here are the Instructions for Setting the Air Mixture Screws. ****The Operational/High RPM Air Mixture Screw is In the Carburetor Bowl in the Center of the Nut or Some Carburetors have Both the Idle Air and Operational Air Adjustment Screws Side by Side on the Top Side of the Carburetor. The Screw Closest to the Engine Is Usually the Operational Air Mixture Screw on this Type Carburetor.The Idle Air Mixture is the One at Top on the Side and Goes Into the Carburetor.   Some have the Idle Air Mixture Screw Going Vertically Into the Top of the Carburetor. The Engine Idle Screw is the One that Moves the Throttle Plate. The Following is the Directions for Setting these Screws. **If the Carburetor was Soaked Overnight in Carburetor Cleaning Solution and the Passages Blown Out with Compressed Air and a New Kit Installed,  then we can Set the Air Mixture Screws. Turn Both Air Mixture Screws In Until Seated. **DO NOT JAM  SNUG ONLY** Turn Both Screws Out 1 1/2 Turns. Set the Throttle to Full Open and Start the Engine. Override the Throttle by Pushing the Governor Arm by Hand and Turn the Operational/High Air Mixture Screw(bottom of the bowl) In Until the Engine is Revving Properly. Now Slow Engine to Idle. Set the Idle Air Mixture Screw so there is No Hesitation when Throttling from Idle to Full Throttle. Now Set the Engine Idle if Required.**** You Can Locate a Breakdown/IPL for this Trimmer at this Addy, http://www.poulanpro.com/poulanpro/indexAction.do and Select Order Parts and Accessories from the List on the Right Side of the Page.
