I never tried the exhaust itself, but I reckon I'm getting a nose for the toxicity of the fumes- smells too lean to me most of the time. I'm going to buy an analyser soon and get away from guess work- some nice ones on ebay at the moment-hopefully cheap. What model do you have Dave? Is it a Gunson? If it is, is it any good? I don't know exactly why but I've a bit of a prejudice against Gunson for being a bit cheap and nasty- but then their stuff is generally cheap! so why not, if it works?
