I also disagree with the "set it and forget it" approach. As I stated, it only takes a few seconds to check it at the beginning of the day. Sometimes its a few clicks different, other times it isn't. But its part of my preflight routine to make sure everything is working OK.

BTW, I've had three deadsticks in two years, and those were because of glow-plug failures, not tuning issues.

To each his own.
