I pulled this engine out of a Poulan saw that was in the scrap pile at the small engine shop. It did not have the pull start on the case so I do not even know what the saw is. I tried looking up the part numbers that are on the jug and crankcase, but did not find them.
In case you cannot read the numbers: crankcase 530028706 Jug 530-037256







I also have a Stihl that I have no clue what it is. Any ideas?
