This listing is for an air cleaner.  It was removed from a Sears Craftsman Eager 1 20 inch mower model #917.383270 with a model 143.414332 3.5hp Tecumseh engine.  It may fit other models as well.  Please confirm that this part will fit your mower before purchase.  It is in good condition.  Payment within 2 days of purchase.  I will combine shipping on multiple purchases when possible.  If you are looking for a part that I don't have listed please ask, I might have one.  Thanks for looking!
