What did you do about the sticky valve? I wouldn't keep trying to run it on starting fluid, you will wash the cylinder walls dry and cause yourself multiple other problems. You may want to use a small gas can with a hose to the carburetor and then just use gravity to feed the gas rather than through the fuel pump. If it was mine I would pull the plugs out and give the cylinders a few squirts of oil, turn the engine over a few times then put the plugs back in. You should be able to pour a little gas down the throat of the carburetor and it should run, and with the gravity feed it should keep going. You may have to tap on the carburetor where the fuel line goes in to free up the needle valve. Good luck, Don
