I took my carb to "experts" and they told me that if Carter built it like that then it must be correct!
I have a friend who also owns a 65GS which was built 6 months after mine and the Blades are also installed back-to-front just like mine.
Have to admit I find it amazing that the Aux Air Blades were installed incorrectly at the Carter factory.
How long did this incorrect production of AFB 2x4 rear carb. Air Blades go on for?

Hi Tom,
Holly Molly, Bingo and Big Thank You. Yes, I see the light!
I just love to understand how things work (up to the limit of my IQ and mechanical aptitude)
This is the explanation I was looking for and can explain it to my other friends with Rivs/AFB's
YES, UNDERSTAND 🙂

Thank You Tom for that explanation and now I have a better understand of the operational differences of the 1 x 4 to the 2 x 4 AFB's
But I am still not clear on the why there is such a marked difference in the Aux Valves design in particular the ordination of the notch.
This time I have taken photos of the actual AFB's in question where you can clearly see the notch location could not be more different.
Would appreciate any future insight from yourself or John (Carb Shop) or anyone else, to why this notch is on the other side.

I am not sure if my question is suited for this forum so do apologize if it should be somewhere else.
I have two 1965 Rivs
1/ 1965 401 fitted with AFB #3921S
2/ 1965GS fitted with AFB Dual Quads #3645SA (front) & #3925S (rear)
I have noticed that the Aux Valves & Weights between the two cars are fitted 180Degs opposed to each other. I would have thought that the Aux Valves would have the same orientation as the AFB’s are basically the same design.
On the #3921S there is a half circular cut-out in the Aux Valves which matches the profile of the venturi support. Refer photo with Red & Blue pencils.
But on the #3925S Carb (Rear Dual Quad) the cut-out is located on the other side the Aux Valve shaft. Refer photo with green cross on Valve plates
If the cut-out’s are in the correct position for each AFB does anyone know what the physics is behind the opposing location of the cut-outs.
Please note that the Aux Valves & Weights are not interchangeable between the two AFB’s
The photos are of an old junk AFB not the Carbs in question.
Hope I have made myself clear in my question which has me absolutely baffled.
Cheers

Is there such a thing as an aluminum alloy intake manifold for a Nailhead?

After using a penetrate like WD40, I find that if you Freeze the item that does the trick.
This works every time with brake connections.

Some cars have different springs (left - right) to allow for the weight of the driver and the camber of the road.
I take it that this is not the case with our Rivs

Good advice from David.
Give me a call on 0419 658 500 and I can walk you through how I made my repair.

Destructive testing.
Fit and check for dimensional tolerance to lower control arm.
Check for bonding of the body to the rubber core by rotational flexing at ambient temperature until fail.
Repeat at high & sub zero temperatures.
Check lateral stability.
Compression, impact & fatigue tests.
Chemical resistance.
So it will be anything that that we can test for chemical, thermal, dynamic & static analysis.

The first lot of bushings should arrive late next week which will be used for destructive testing.
Will let you know how they perform.
Can anybody verify that the the bushings for 65 are the same as 63 & 64?
(USA vendors offer the same bushing across all there years)
The 3 of us involved with this project all own 65 Rivs.
With the COVID lockdown we are not allowed to travel more than 5km from home!
If we get nicked its a $1,650.00 fine.

Lots of us down here in Australia have ordered rear bushing form lots of vendors and have been told
that what is offered is a direct or near direct replacement bush. Not so.
In some cases we have had road worthy compliance rejected as it's obvious that the bush replacement is not as per OEM.
So we have to spend big $$$ to get them custom made.
Some of the pricing vendors are asking for non OEM bushes is crazy.
Thank you for your feed back.
Bushes are for the rear lower control arms (4 Qty) and the rear upper "adjustable" control arm (2 Qty)
The upper and lower use the same bushing.
They can't be used for the front lower control arm. They are different.
Tooling samples that we have been using have been as per 1965 Riv.
We make the assumption that bushings are the same for 63 & 64 but this needs to be verified.
(it amazes how there are so many small design changes that Buick made between 63, 64 & 65 i.e. door hinges)
Yes the bushes will most likely be shipped in bulk over to the USA and offered to a vendor(s) to reduce S&H
but we have yet to figure that out.

Frustrated with the 2nd rate offerings a small group of 1st Gen Riv enthusiasts with OEM auto industry connections have been in development of an exact replacement of rear bushings. Tooling completed and about to evaluate full production samples, and yes we‘re excited. These are dimensionally 100% as original and with the same hardness rubber. Volume production is being done by a specialist (not Chinese) manufacturer of suspension components with facilities approved and used by Toyota and other major manufacturers. After many months we’re hopeful these “made for purpose” bushings will be available mid November. Pricing is yet to be determined but we know will be well below any of the current sub-standard offerings.
They’ll be available in pairs so let us know your interest or feedback.
Cheers

Photos show lots of rust. But there has to be more rust you can't see until you start attacking & chopping sheet metal.
Unless it has some sort of sentimental history, I also agree that its a parts car.
Has anyone done a full resto and not spent way more than your original budget?

Please note that the LEDs do not dim like incandescent bulbs.
Wonder if there is a way around that.
And depending on your preference you have a choice of Warm White or Cool.
Chart above based on WW.

In the Nov 2017 Australian Region REVIEW is a list of Super Bright LEDs for 1st gen Rivs.
I have replaced all my interior bulbs with LEDs as per this chart and very happy with the result.

Small emblem Gran Sport from November?
Can anyone else verify that?
If true, then the small emblem Gran Sport was only available for 2 months.
-
The vinyl roof was an option, but only available from mid year.
Was it factory installed or fitted at dealership?
Or both?
-
I never understood how you could go to a dealer and order a Buick Riviera with no options.
In fact you could order equipment delete.
Keep in mind that the Riviera was marketed as a personal luxury car.
Correct me if I am wrong, but Buick was a luxury car mainly for the conservative buyer.
But also, I would think that the Buick buyer was more price conscious than say a Cadillac buyer.
-
When the 1965 model year was launched was the Gran Sport option available from day one?

Did PARISH also manufacture the Differential Housing and lower control arms?
Also, who manufactured the Differential.

Thanks Jason, That was quick.

Hi All, My friend is doing a frame-off resto on a 65 and has found some stampings on the back passenger side as shown in the photo.
Does anyone know what PARISH is about?

Carter AFB - Aux. Air Valves
in Buick Riviera
Posted
Thanks for the reply Jon.
Helpful in trying to understand the aerodynamics across the "Flats & Holes"
So with the Carter drawings incomplete we will never know with 100% confidence that
the way the holes are located on the 2x4 rear AFB are as per the engineers design for this application.
I like your Carb selection statement:
The most expensive carburetor you will ever buy....is the wrong one for the application that you attempt to modify!
