After having my FI sytem "tuned up" (meaning adjusted properly through all the ranges) recently, AND in talking with meistermechanik Gernold Nisius at SL-Tech, I think Gernold's assessment is correct: with E10 or E15 being the standard these days, when you adjust your system for "optimal" performance (using the split linkage method) you will probably be on the richer side, and probably be WAY over the older CO and HC standards. The gas is very different than it was in 1968, and in order to run properly the system is going to want a different mix.
Come to PUB, learn about the system, and learn to lean it out yourself. Your car may run like crap, but it will pass the test. Or, at least CALL Dan Caron--he is probably familiar with the tests you must pass in Canada.
FWIW old cars like this are not even a blip on the radar screen so we leave 'em alone, for the most part, in the USA.
