Here is an experienced #5600 K&B Sportster .20 engine with carb and firewall mount, but no muffler. Turns smooth with great compression.  Comes, as shown, with original grubby box. Engine shows evidence of being mounted and very little run time,  may need more break in time. Recently acquired as part of an estate.  $12.00  shipping in U.S. Can be combined with other auctions to save on shipping costs                                                        

NOW THE FINE PRINT: I want everyone interested in my auctions to be aware I am the only guy here and I have a full time job which takes me away from home a lot. I do not always have online com available. I try to ship twice a week, usually on  Tuesdays and Fridays.  I will do my best to make sure you are happy with the deal, if not PLEASE let me know, we can work out any misunderstandings.
