Hi, my roommate just brought up an older (96-03 I believe) kx 60 2 stroke. We tried kicking It, but the lever wouldn't even budge. It hasn't been ran in probably 8 years, just setting in a garage so we decided to take it apart. The filter is trashed, and the oil was yellow, other than that everything looked fine. My question is, because I've never even seen the inside of a motor, what do I need to look for that could be broken? I took apart the kicker side of the motor and all the gears look fine in there. I can post pics if needed.
