What I have is an 3/4" ALpha carby which is a copy of the Schebler Model D.
As you can see by the photos, its had a bit of knock, and the air intake is bent about. Looking for advice on how to straighen it or am I better of leaving as is?
Secondly I have seen on some carbies a threaded flange plate to allow for bolting the carby to a matching flange plate, are these available or have they been custom made?

Flanges were most likely custom made.
As to straightening your carby...
You can only bend brass once so it will need to be annealed.
Take all of the air valve parts out of it.
I have had good luck with parts like your air horn by heating it with a torch to a dull red. Hold it with a pair of pliers till the color just goes away then just drop it in a bucket of water. You will need to do this in low light to properly see the color changes.
This will allow you to bend it once again and most likely get it quite close.
Once you have done that I would take a plain old screw type hose clamp (not a mini clamp)and put it around the air horn and that will most likely compress it back into shape as you tighten it.
Once straightened you can silver solder it along the crack
Hope this helps

That insert inside the air horn is not standard either,they were usually put in to compensate for

Thanks for the tips,I thought that would be the case with the flange. I like your idea of the hose clamp, saves belting it with a hammer.
I wondered what it was there for as I hadn't seen it on any others. I have removed it.

New to this site. Today I picked up an Alpha Model D carburetor. It's missing the top plate (is that the slide?)but has the float and all fittings. Anyone need it for one of their projects?
