I have a 28/36 DCD sitting on my 1100cc at the moment, goes good
Alot better then the small 1.25 SU I had on before.

I asked the guy a few Qs before the auction closed.

It was a 32DIR carb - looked it up on the 'net and found it was used on Alfasud 1200cc and some Renaults.

Chcke sizes were 24mm primary, 26mm secondary. About right for a 998 or 1100, a bit small for a 1275 according to Vizard's Weber DCD suggestions.

I had a 32/36DGV on a Gemini once (26mm / 27mm). It was great - a lot easier to calibrate than an SU. Should have kept it for use on a 1275.

Good things about these carbs- they do stay in tune, and because they are a progressive 2 barrel carb, the primary barrel is usually jetted for economy. Yet it will still howl when you gun it and open the secondary barrel.

Downside- jetting it properly. Many people don't understand them.

Dunno why people would misunderstand them, I found them a lot easier than an SU.

With an SU you have to buy dozens of needles to try. They are not in a logical numerical sequence, lean to rich. Too many variables to get the right setup. You can only get it close without filing needles.

With a DCD/DGV etc you buy a few main jets and try them. Need more fuel, go up a number or two on the mains. Need less fuel, drop down a number or two. The jets are in a logical sequence 125, 130, 135,140 etc. Tune primary 5-10 leaner for economy.

Fine tuning at the top end can be done with the air corrector jets. Air correctors work in reverse - smaller jet = less air so more fuel and a richer mixture.

If you want to get really accurate play around with different emulsion tubes and pump jets too. It was all available over the counter at my favourite speed shop (Stree Performance in Beverley Hills, Sydney). Back in the early 90's the jets were about $1 each. The carbs were approx $40 off any 2litre Escort or Cortina.

Only disadvantage I can see is the manifolds are a bit restrictive.

If it hadn't been for the complexities of hooking up the Auto kickdown to the Weber, I would have bid on it for my Moke.

I didn't mean these Webers were hard to jet, lol- they are so easy. Like a sidedraft Weber or Dellorto is too. Once you suss out where it's lean or rich, it's easy. Jets now cost a bit more than $1 each though.
My last foray to Carburettor Service Co for Dellorto jets cost me $99.
I only bought 2x 150, 2x 155, 2x 160, & 2x 165 mains- and 2x 170 air correctors..

Well I just put a 45 DHLA on my 1275 and it is worth it. As much as seting up the manifold and the linkage was frustrating it is nowhere near the frustration twin carbs cause you and the power gains are very real.

I'm sold but in terms of cost its not as cheap and easy as it might seem. I bought the pre emissions Italian 45 Dellorto of ebay for $145 with a ramflo filter (Sweet), but then when you consider the manifold ($50 which broke so I got the good Redline one $160) larger chokes ($50 used rather than $70-80) linkage kit from crappy Lynx which I had to modify to make it work ($55 and the extent of mods would have been considered unreasonable with any normal retail product). I was lucky in not needing different mains, airs and corrrectors (yet) otherwise it would have been another $70 plus you need a fuel filter (cheap) and air filter element and you might have to put a kit through the carb ($55). So altogether you might be looking at $400+++ and thats something to be aware of before you go in.
