I'm always a sucker for vintage tune-up tools, and one carb tuning guide I've recently come across(published by SU) gives instructions in the form of a CO meter, or as best as I can tell what was sold as an exhaust gas analyzer here.
Looking a bit around Ebay, I've found 70s era meters made by Heathkit and ASI. They seem to sell for similar prices for similarly complete ones, so that's not really a factor.
Does anyone have experience with these? If so, can anyone recommend one over the other, or possibly an alternate brand? I bought a Penske branded tach-dwell, or really an automotive multimeter, from a member here back in the spring, and it's been a dream to use.
