Check that the air filter on carburetor is correctly fitted and that the filter element is not blocked. If the filter does not allow air flow it will affect or prevent engine running and by applying the choke the engine will run but it will be using excessive amounts of fuel.

Pull off the exhaust, does the piston look ok?
If scored thats not good.
If ok check fuel filter , pressure test lines or remove and check for cracks. Just a start but check easy stuff 1st or get back to me with more info, cheers

From the fuel tank to the carb, from the carb to the primer, from the primer back to the fuel tank. The bulb sucks fuel through the carb excess fuel is returned to the tank. HTH

Clean the muffler spark arrestor screen and check the cylinder port for carbon build-up at the upper edge. Try presetting both carburetor H and L adjustments (from lightly CW stops) 1-1/2 turns CCW each. Start the engine and allow to warm up. Pull the throttle wide open and adjust H CW until the engine speed increases, but still 4-stroking. Correct setting is when the engine 4-strokes, but immediately 2-strokes when cutting. Allow to idle and adjust L for smoother running, yet allows the engine to 'follow the throttle'. Set idle speed to keep the engine running, but doesn't try to move the chain. You may have to look closer at your carburetor if the above doesn't help. Go to:

for an excellent article (but poor pix) on Walbro carburetors, but related to most all 2-stroke carburetors. Hope this helps!

SOURCE: how to replace the fuel primer bulb and fuel lines
I just did a primer bulb not too long ago, but I don't remember what equipment it was on. They are generally easy to replace. First, remove anything that is retaining the bulb assembly, such as cover plate. On my Homelite chainsaw, I simply pried it out with a small screwdriver.
The replacement part itself has two barbed stubs that the two fuel line hoses push onto.
Make sure that you keep the fuel line tubes above the fuel level at all times to prevent leakage.
