OK I had a friend of mine give me an old Craftsman Chainsaw to convert, but I am having a little trouble identifying the engine. I read a bunch of posts saying that alot of Craftsman saws used Poulan engines, but this doesn't seem to be a poulan. The cylinder head itself is quite large with an apporx. bore size of 1.90". The bottom half of the engine is part of the saw case itself, kinda of like a Sachs engine. The carb is Walbro but a bit larger than your average run of the mill walbro carb. When I set this engine beside my Homelite 45cc conversion it seems quite a bit larger. The only identifying mark I can find on the cylinder so far is a star with 2 lines through it. Well what do you think ? What is it ? I can try and post some pics in the next day or so.

Thanks in Advance
Scott
