I'm in the market looking for a classic cabover and found a KW K-100 w a KT 450. They say it ran when parked 10 years ago. It has not been run since. I'm going to look at it. What should I look for on a non-running engine??? There is potential there that I could buy and engine that is scrap! The whole point in my interest is that it is a K-100 with a KT cummins. What should I look for? Any ideas?
