Just a little some thing I found on 4cyle .com
Thought some of you might enjoy it.
It's suppose to work, But I have yet to try it out. All you need is a mic and a computer, the programs free.
RPM from Sound
Evidently 0.500000 fundamental cycles per minute is perfect for single cylinder engines, and if you set the program to listen for a specific rpm range it's even more accurate(supposedly) The problem with that is the program won't read listen for the rpm above or below what you set.
