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!

Testimonial: "Thanks for the help. A very complete answer should cover all the possibilities."

SOURCE: why will homelite 290 chainsaw not start?

Make sure you have blue, snappy spark at the plug (set at 0.020"). If ok, put some fuel mix in the plug hole and try to start--it should pop several times. If pops, then check the fuel system. Check the fuel filter, air filter, and muffler for plugging. Check the fuel lines for decay or other damage. Make sure the carburetor fasteners are tight.
