The venerable DCOE is the Weber's premier Carburetor - which is still the standard by which all other carburetors are measured. It is unsurpassed for full-race use, yet its infinite tune ability by way of interchangeable calibrated parts allows it to be tailored to suit any engine and application. Hardly enough can be said about the DCOE. Its features include: ball bearing throttle shafts, piston type accelerators pump circuits, a wide variety of throttle bore sizes.. and, of course, the excellence that is Weber.

I have a 94 JDM spi 1275 that I want to switch to a carb setup. I have a stage 3 head with a 1.5 rocker, full header and exhaust system. I plan on switching the cam out in the next year. I see you have a kit. But will the S.U carb you spec handle be enough carb or shoul I go to a weber 45 dcoe?
Answer:
The 1 3/4" carb is a great option and would allow you to simply upgrade from the SPI option. On most dyno test the SU is almost as good as a very tuned Weber. The key is that to get the benefit from the Weber delicate tuning is needed. Unless you have the option of taking your car to a Dyno- go with the SU
Question:
I have a dual SU set up 1972 Austin 1275cc. If I want to change to a Weber, what am I looking at. Is it better fuel delivery? Is it a full kit change over type of thing?
Answer:
We do offer a weber carb kit that will fit your mini. We have better luck with the stock SU carbs, but a weber is also good. Here is the link https://www.minimania.com/part/P4-004/

Question:
I have a stock 1275 engine. Can I use a 40DCOE? will it be jetted and ready for this kind of engine? Will I need to know any thing special to get this going? Thanks
Answer:
Complicated question, yes it will run as you receive it BUT to be honest, you will not get big performance gain unless you have it tweaked with the use of a Dyno. And probably more important using this intake manifold will not allow the use of an air cleaner and may in fact only be able to use short intake stacks. If you have your heart set on a Weber system I would suggest this- it is a simple bolt-on with no further tweaking needed: https://www.minimania.com/part/P4-004/

The name "Weber" says performance; and a Weber on a Mini has always been considered the ultimate! The side draft Weber range used is the "DCOE" series 40DCOE.
This very famous high performance carburettor is available as a bolt on kit for the A-Series. Includes 40DCOE carb (19550.174), linkage & 3.5" manifold.
One of the common problems with side-draft carbs is the choice of the carb size in the first place and the choke size in the second. The trick with carb sizing and choke selection is basically one of choosing a size which provides the engine with the air flow it needs without overwhelming it. Although carb selection should really be done after you know the flow characteristics of your cylinder head, we can provide the following guidelines: if the choke size required for your engine is 35mm or less you should be using a 40DCOE, for all choke sizes of 36mm or larger a 45DCOE should be used. NOTE: a 40DCOE with 32mm chokes will flow more air than a 45DCOE with the 32mm chokes! A 948cc with a modified head, semi-race camshaft and LCB exhaust typically uses a choke size of 33mm, a 1098cc with the same set-up uses 34mm chokes, and even a stock 1275cc only needs 35mm chokes; all of these engines should use a 40DCOE. A full race/street 1098cc could use chokes between 32mm and 36mm chokes making it borderline 40/45DCOE. A highly modified street/race 1275cc could use as much as 38mm chokes; definitely 45DCOE range.

I was wondering which Weber Kit you would recommend for my Bugeye. It has a 1275 with a performance cam ( I don't know the specifics since it was installed before I bought the car) tube header, and it looks like the vacuum advance on the distributor was removed. I'm thinking the 45 might be the right choice.
Answer:
We would suggest that the for a street 1275 the 40 DCOE would be our first choice but we also suggest that from a bolt-on performance standpoint you should consider the DGV set-up: https://www.spridgetmania.com/part/P4-004/Classic-Austin-Mini-Dgv-Weber-Carb-Kit-Includes-Manifold-Carb--Air-Cleaner From my personal experience, the DCOE is the best if you are willing and able to 'tune' it while the DGV is a great bolt-on Weber with a soft touch for fuel economy with the same top-end performance of a DCOE.

Question:
I would like to know if your intake manifold is 40mm diameter on the carburetor side?
Answer:
I'm pretty sure they measure it on the manifold side.

So you have a nifty Weber DCOE or S&K Racing sidedraft carb setup for your vehicle. You're ready to chew gum and kick butt, and you've run out of gum. You bolted on the carb in place of your SUs or Zenith-Stromberg and voila! You have worse gas mileage, and the power gain is slight enough to be psychological.
Last time we chose a manifold based on flow volumes, and a carbie based on personal choice, but which combination is best on this engine? With the engine finished, it is time to look at a variety of carburettors, inlet manifolds and exhaust extractors, to fnd the most suitable combination. There are a lot of fgures, but they are necessary, so bear with me.
One of the common problems where sidedraft carbs are involved is the choice of carb size in the first place and choke size in the second. The trick with carb sizing and choke selection is basically one of choosing a size which provides the engine with the airflow it needs without going over the top.
