Actually, I have one. It's not a bad device and does work, but I'd like
something more precise, and easier to use. You have to remove hot spark
plugs and the hot glass plug (I just can't seem to remember not to grab
onto them), and check two different cylinders. I also had trouble
seeing the flame reflection on sunny days, and the last time tried to
use it I fiddled with the mixture so long the periscope melted.
Sunny days are not usually a problem here, but that's when I like to
tune up the car!
