I have a 900 T8 fuelled by the K-Jet system, so I'm pretty much in the dark when it comes to mixture. I'm getting pretty fed up of having to go to a garage to have my mixture checked after cleaning the air filter. Half of the time, they get it wrong anyway ... by wrong, I mean nowhere near as good as my normal SAAB independent garage who often need a week or so notice to get in. A slight tweak gives me better power and performance ... usually. So, I've been looking at the Gunson Gastester. In Halfords (I know <tut> ), their display case had the instruction manual still in the box. Am I right in thinking that reducing CO to as low as possible gets the car as close as possible to stoich? It would appear so from the graph. I take it this is not just a case of twiddling the mixture, but adjusting the basic idle too. I'd appreciate hearing from people who have this kind of tool, especially B201 engine owners; 900 or 99. How useful is it? How easy to use is it; not that I'm scared off by having to spend some time fine-tuning. Is it a good tool? Paul 1989 900 Turbo S http://saab.go.dyndns.org/
