I'm going to pick this up guy says it doesn't run may have low compression. I figure for 10. Its got to have some good parts on it. I will probably take it apart. What should I look for to know its not worth messing with? I have a viper 99cc engine also Would the parts interchange? I would think even if they dont 10. I'm not out much. Maybe its an easy fix? Looks like its mounted in a generator frame.
