BTW, my understanding is that copper pipes are actually a copper-
nickel alloy, to avoid (or at least reduce) fatigue problems. I've also
heard of steel lines with some sort of internal and external plating to
avoid corrosion (for some reason copper-steel-nickel comes to mind).

It could be the bypass valve. Instructions on how to adjust them
(even if non-adjustable) have been posted here before. If the carb hasn't
been rebuilt recently, this could cause problems (split diaphragm, etc).
There's a strong chance of somewhat worn throttle shafts leading to leaks
and mixture/idle problems. Try the spray-carb-cleaner trick to check for
vacuum leaks.

White? That would normally indicate that you're burning antifreeze
(i.e. head gasket leak or head crack). Unless my memory is failing, which
is of course possible. You might want to retorque the head for safety and
hope it goes away. Blue-ish is normally oil burning, and black is over-rich.
