New carb on '85 Corolla, pass emissions?

Hey all - I may have posted this a while back, I can't remember, so my
apologies if I have. Car is a 1985 Corolla SR5, 221k miles. Runs well
but uses about a quart of oil every 3000 miles.

I want to put a Weber carb on it to increase the horsepower, right now
it's making 70 hp (flywheel). What i'm worried about is the emission
controls - the current carb has lots of vacuum lines running to a
variety of sensors and whatever. Weber told me that "these will be
plugged off, cleaning up the underhood area".

Will this make me fail emissions? Or can I still hook up some of this
stuff somehow?

Thanks!

(The exact carb I want to install is a 32/36 Weber 2-barrel, replacing
an Aisin 2-barrel.)

You should be OK as long as your PCV valve and EGR system along with
your gas vapor recovery cannister are still in the circuit. None of
that has anything to do with a carburetor.

There may be quite a few systems (air injection, EGR, etc.) that depend
on these vacuum lines being connected.

On the other hand, what are the regulations in your area? Out where I
live, anything over 25 years old is exempt from emissions tests.

AFAIK, the car as EGR, PCV, and the canister, along with a bunch of
other circuits I couldnt name off the top of my head (fuel cut on
deceleration among others).

I'm not sure of the regulations but I don't think they check under the
hood, they just do the tailpipe test.
