I don't know ... but most likely the charcoal itself doesn't have to be
replaced. There is a fiber/wire mesh filter in the bottom of the unit, most
likely it's all that needs to be cleaned or replaced.

I think it depends on exactly which emissions setup it has. On your
friend's TR6, the float bowl vents are connected to the top of the canister,
which also has air flowing into the carb bodies. If the canister becomes
clogged (or if some of the orifices are missing), it draws a vacuum on the
top of the canister and on the float bowls, which prevents the carbs from
drawing fuel. The anti-run-on system actually does this on purpose, to help
the engine die when the key is turned off.
> - is it even a good idea to remove it at all?
Whether it hurts or helps depends on what you have, and what you do with the
disconnected lines. Personally, I like to leave emission systems intact,
unless I have a good reason (like lousy performance or gas mileage) for
disconnecting them. The carbon canister doesn't hurt either of these
directly, although most Triumphs seem to be set up such that the purge air
flowing through the canister makes the engine idle leaner. The overly lean
idle can make them run rough, or overheat.
