Sorry, that's not precisely what I meant, though now that you point it out,
it seems like what I said. ::blush:: My reasoning went something like this:
1) In doing a tune up on a car, set the timing first (within reason -
obviously the carbs have to be somewhere close to correct for the car to
2) Each combination of cylinder compression/carb type/carb tune/timing has
its own little power curve, and its own set of dynamics. Change anything in
the mix from stock, and the manual's specifications for the rest become
3) If your timing is way off, no matter how rich/lean you set the carbs, you
may not be able to get the car to run properly.
Therefore, if setting the carbs to the end of their adjustment doesn't
improve the running of the car, perhaps it's because the timing is off in the
first place. The car may appear to have some of the symptoms of running rich
or lean, but that's just an appearance; go back and check the timing, then
try resetting the mixture. I didn't mean to imply that the timing has
something to do with the mixture, but that the mixture may be irrelevant if
the timing is off.
Sorry. Early morning mutterings disease.
