I still have cad, I decided to repair a Husqvarna 240 out of my own pocket from the dead tool loft at work that had a torched piston. It runs perfect but I need to keep it from those who grab the gas can and don't check it.
I have an s145 which is just like the s160 and they are a far cry different than the poulan craftsmans and imo an improvement. See my post here.

Mr justsendit seems to toot his own business horn a lot in that group and bury others, I left that group a long time ago because of the constant oil arguments.
