Pictures of Amx12

I appreciate the pics for my collection, Eric!

We can only wonder which bowl and nut came on it originally.

Recorded at Davenport, Folks,...

This aluminum AMX13A, (aside from a Linkert bowl and throttlelever),

AMX13A top4.jpg

has a clamp-on airhorn,

And the bizarre lowspeed needle!

Schebler had no rules.

It gets better, Folks!

This is apparently not an AMX, but an H169...

This feels like the right thread so hope it’s ok to continue on with the barrel theme?

I’m searching for information about the Linkert MX12. I already have a Shrebler AMX 12 on my peashooter but, in terms of size, this is a different beast

And generally, why did ”the racing department” switch from the barrel type to throttle plate (MR’s) carburetors?

I have no experience with the barrel type carburator but it seems to me that they are an idle or full throttle carb with poor transition in the mid range. The butterfly carburators power throughout but do not have the topend of a barrel type.

I have no real experience either, Martin,..

But but the barrels cost nearly twice as much as a conventional carb.

With a fraction of a market.

PS: Reviewing my limited literature and pic collection, I find no references to a Linkert MX12, but that just goes to show how little has survived...
(It seems like they went straight from the 'barrel' MR2 to the 'butterfly' MR3.)
But we would very much enjoy pics of your AMX12, if convenient!

PPS: Tommo provided these, but will have to explain the New Zealand prices....

PPPS: Note for posterity how curiously the "De Luxe" is shown with the bowl indexed in an improbable position.

Yes, I've been hunting high and low for info about the MX12 but so far all in vain.

The only one I’ve seen in the flesh (before this one) is the one mounted on the 80 c.i flathead hill climber at Wheels Through Time Museum.




Some (bad) pics of the MX12 (the last one from the museum)

…and the AMX12 (will need some love)

I appreciate the pics, Martin,..

But its hard to archive the MX with certainty without viewing its model stamp.

The total lack of a highspeed needle baffles me!

....Cotten
PS: Folks, I suspect the H169 in post #64 might apply only to the cover or some other part.

We may never know.

Will post better pics (with stamp) when the carb is in my hands

It may be such 'racing' carbs were produced individually, Martin,...

Please note the two examples of MX12 have different castings!

Looking forward to it, Thanks!

Some better pics of the MX

[T. Cotten]

What a rare piece, Martin!

Was the consensus the A stood for alcohol?

As if the lack of a highspeed needle wasn't confusing enough, note the lowspeed has a Schebler knob with an apparent air port to the needle itself. Note also the rectangular 'window' upon the casting which showed up on later Model Ms to shroud a hole for air correction to a venturi.

Your pics are greatly appreciated, but its a riddle wrapped in an enigma for me!

PS: Can anybody explain the covers on the AMX8 and "H169"?

It would seem they were over the main nozzle.
