The top cylinder is 115 and the bottom is 105. Would that mean bad new's? it kind of sounds like in knocks but it's not to bad. The motor when I try to plain off goes for around 30seconds then wants to slow down and bog out. If I slow down it will plain off for a couple seconds sometimes. Let me know what you think i'm dealing with? Thanks alot.

compression sounds ok. I had a similiar problem with my old johnson, and I cleaned out the carb (which was filthy) and changed the spark plugs and she ran great after that.
