Start with 1 turn out from bottom on both and adjust from there as needed. The screw closest the engine is low speed mixture adjustment and the outer is high speed mix. adj. Hope that helps. Dwain

The tool you need is available from Randy's Engine Repair, on his E-Bay store. The price is about $10., plus $3. shipping. Phone for Randy's is (937) 927-5665. It is usually busy.
Ebay item number is: 390025452838. Buy it online. I got mine about a week after I ordered it.

L is for idle speed mixture and H is for full throttle mixture. Adjust H, when engine is warmed up, with full throttle--adjust for high speed, but 4-stroking which should smooth out just as soon as you start cutting. Allow to idle and adjust L for smooth idle, but rich enough to allow the engine to 'follow the throttle'. Set idle speed screw to just allow the chain to stop moving.

Turn both screws CW to stops (lightly), then back out each CCW 1-1/2 turns. This should get the engine running if it will. If it does not, check the lower diaphragm on the carburetor for hardness or cracking. You appear to be running on prime only--the carburetor doesn't seem to be pumping in fresh fuel. You may need to do a carburetor clean and re-kit. Check the fuel line condition and the fuel filter in the tank for plugging. Make sure the muffler and air cleaner are not plugged. Once you get the engine to continue running, warm the engine up. Open the throttle and adjust the H needle CW--the engine should start to speed up, but still 4-stroking. The proper setting is 4-stroking, but immediately 2-stroke when cutting. Release the throttle and adjust L needle CW so that the engine runs fairly smoothly, yet will allow the engine to 'follow the throttle'. Set idle speed screw so that the chain stops turning, but the engine continues to run. Hope this helps!
