Perfect!! The part # 3402522 ( "K" in the Dr. Rebuild pic) should be what you are looking for. Hope you can get this stuff down yonder!!

Here's a clickable link to the above post from CeeDee:

That might be the right part on e-bay, but I would go with the Doc, because it would more likely be correct. Adams' Apple38541.797650463

Thanx for that everyone. I'm off shopping at the Doc. I hope. Wee query for Ken re the cold air for max power thing... Ken, if the Air Cleaner thermostat set up is working correctly, once the engine is warm would not the air supposedly be only coming in through the cold route anyway at that stage, with the warm air option completely closed off by the flap ? Or does it still mix some warm stuff in there anyway.
(He asks without the air cleaner sitting on his knee in front of him to look at !)

FYI - The Doc's customer service can be trying at times, but you never know. He's not as involved any more (semi-retired), but does have a couple of very nice laddies on the desk that will help in getting you the parts you need.

The air in the air cleaner assy will always maintain about 120 degrees F.  This is once the exhaust manifolds get hot, which takes less than a minute.

Keep in mind, this is for optimum fuel control and emissions with a carb.  That does not mean it is always best for performance.  A colder air supply will create a denser air volume, and thus more air into the intake and into the cylinder, which in turn produces a bit more power.  It may not be noticable in street use, but might show up on a dragstrip.

Well I finally got round to fitting it. GOOD NEWS... the
two vacuum controlled flaps still operate. BAD NEWS... I
would have thought that after driving around for 15 mins
it would have warmed up enough to open the flap it
controls, but no so I swapped the hoses over
which attach to the sensor just in case it makes a
difference, and still no joy ...if I touch the
"plunger" in the sensor ever so lightly the flap opens
nicely, but on taking my finger away it closes again.
Is there an easy way to test the sensor's operating
properly / at a correct temperature (whatever it is) ?

On the plus side, as it is around 6 degrees C here
currently (winter has arrived) - that's around 44 F
in your talk - she does seem to be smoother on start
up from cold !

AHHHH the land of the long white cloud.  CeeDee, do you need your car to be totally original?  If not, get rid of that original air restricting can on the carb and put a Holley 600 on with choke and full flow air cleaner, then just wait for the engine to warm up.  I believe you can do that in Un Zud and remove all the anti-pollution crap while you're at it.  You'll then have a car that both looks good and performs like crazy.

P.S. Just don't drive too fast or you'll run out of road and end up in the drink.

Well I'll be, a for real ocker ON C3VR !

Gidday mate. ( sorry, couldn't resist !!! )

Car is already clean of all smog stuff... air pump is
gone altogether, and as far as I can make out anything
to do with emissions has been removed or disconnected,
even the EGR is disconnected.

So I'm just tinkering with bits that seem to do no real
harm when they're connected. Not looking at all to
restore to original.

However I kinda liked the idea of having warm air
feeding the engine while it's cold. Not particularly
stressed about it at all though...

Cheers
Kiwi Chris

P.S.
Northern Territories... your Vette wouldn't make it
between gas stations out there would it ????

Always nice to hear a Kiwi and Oz-man banter back and forth.  Such amicable animosity!  Just never thought I'd hear (see) it on the C3VR forums!

Goodonya mate!  You both just need to sit down and discuss it over some tucker.  I know, I know, Vegemite (spread on anything) for the Oz-man!

I onlhy just make it between gas stations but I can drive as fast as I like.  Vegemite invented by Kiwis?  I don't think so!!!

Only problem is, the bloody company is owned by the yanks now just like Arnotts

I bought a 1982 just recently.  I noticed that the air cleaner louvers were not closed when the car was cold (or not running).  

I added back the missing stove pipe and started tracing the vacuum lines.  

The vacuum line coming from the TBI to the temperature sensor is missing.

Further investigation, the vacuum line that is suppose to run from the TBI to the temperature sensor has been cut off and capped.

Can anyone tell me what that would do to the engine running in cold weather?
