When the engine stops running, remove and inspect the spark plug. If the spark plug is dry, (1) the fuel filter is probably clogged and restricting the fuel flow, or (2) the carburetor needle valve needs t be opened approx 1/8 turn for a slightly richer mixture. If the spark plug has carbon deposits (or is wet and smells like fuel), (1) the air filter is clogged, or (2) the spark plug needs to be cleaned / replaced, or (3) the carburetor needs to set (closed) for a slighly less rich mixture.
