1” SU Carb - k8207418 - 30-07-2022

I’m looking for a rebuild kit for a 1” SU but can’t find a ref to 1” anywhere 
Do new parts exist for these carbs ?

Burlen Fuel Systems.

The Worlds Sole Manufacturer of Genuine SU Parts - SU Carburetters

1" are either OM type (Vintage) or UBA type (Post vintage Morris 8).

Now looking for a manifold

I've owned a 1936 Series I Morris 8 Tourer for almost 50 years so I'm very familiar with the 1" carbs.

As mentioned above by Parazine:

SU OM carb - 1930's S.W.B. Morris Minor

SU UBA carb - 1935 to 1938 Morris 8

A UBA type will bolt onto a standard post 1932 manifold (Late Box or Ruby type) with an adapter to turn the studs through 90 degrees. An OM type should bolt straight on, depending on the exact fitment, as the holes in the inlet will line up with the Austin manifold.

Here's the adapter mentioned above:

   

It's easy to make one up from a piece of 8mm plate, small bits of this are available on eBay.

RE: 1” SU Carb - k8207418 - 31-07-2022

That’s great
I thought I would need a new inlet and exhaust manifold

RE: 1” SU Carb - k8207418 - 03-08-2022

So is this a UBA or OM
Thanks

RE: 1” SU Carb - Parazine - 03-08-2022

UBA. The giveaway is "1930" cast in the side. Wink

RE: 1” SU Carb - k8207418 - 09-10-2022

I’m looking for some sort of filter or ram pipe to finish off the 1” UBA
Any suggestions
