The reason for the engine smoking and uneven operation was an inadequate mixture of fuel and air. The reason for the change in the composition of the mixture was the nozzle that protruded from the carburetor housing. Black smoke from the muffler is a sign that the engine is getting too much fuel that it cannot burn through. Sometimes the same symptoms occur when the air filter is dirty.
