does your "carb heat"
just apply heated air to the regular air intake to the carb or manifold? or
is it an "alternate air source"


The former, I believe, though I'll check it out. It's an archer (we also have
a dakota, which should be similar). There is an "alternate air" lever, but
that's an alternate static source.


Technically it's both. When you use carb heat in an Archer, it
bypasses the regular intake path / air filter and sends unfiltered
warm air to the intake manifold (that would make it an "alternate air"
source). This is quite useful when your intake is blocked. I've had
to use it twice for that reason. Once because of snow buildup on the
filter and another time when I somehow sucked up a plastic supermarket
bag (commonly seen floating around in thermals here in the southwest).
