26cc blower homelite will not start

Try placing some fuel mix in the spark plug hole and try starting. It should pop a few times--if so, then concentrate on the carburetor and fuel supply. Check the fuel filter, air cleaner, and muffler for plugging. Check the condition of all fuel lines. Make sure that all carburetor fasteners are tight. Does the machine have a primer bulb and does it fill with fuel when pumped? Have the H and L jet screws been turned? If so, turn both screws CW to stops (lightly), then back out CCW 1-1/2 turns each. This is a basic setting and the engine should start and run. Pull the throttle full on after warm up and adjust H needle CW so that the engine just starts 2-stroking. Release the throttle and adjust L needle CW so that the engine idles fairly well yet allows the engine to 'follow the throttle'. Set idle speed screw so that the engine continues to run, but speed is fairly low. Hope this helps!
