It seems that some of you are prescribing accurate methods for reducing the amount of exhaust smoke while the engine is running. My blower smokes very little while the engine is running, but smoke pours off the metal of the muffler (not out the exhaust hole) after the engine is stopped. While this could be caused by unburned oil being spit into the muffler, very little, if any, oil is spit out the exhaust port while the engine is running with no muffler.
Several facts which might be of use:
The carburetor, fuel filter, fuel lines and spark plug on this engine are all brand new.
The smoking decreases when the spark arrestor is removed.
The fuel in this engine is part of a batch that I mixed two or three days previous to running the blower. The other part of the batch was used in my weed trimmer, which runs fine without smoking at all when the engine is off.
The area on the muffler from which the smoke arises is a dull grey, while the rest of the muffler is bright and shiny.
