Hi all, I am wondering if anyone can clarify what is the correct arrangement for the linkage for a DCD carburetor on an Abarth? The first two photos are a later type DCD carb I have sitting on the head along with a 600 rocker cover (aftermarket alloy one). The third photo is an earlier DCD3 carb. Note how on the DCD3 carb, that the linkage arm on the carb points down, but on the later DCD carb, the linkage arm points up.
It seems that by looking at various photos I have seen, the linkage on the Abarth cars points down. I also understand that a DCD7 carb was "standard" fitment? Using an earlier DCD carb (DCD3, DCD7) the linkage rod from the rocker cover would push to the passenger side of the car.
However, with a later DCD carb, the linkage rod would pull to the driver's side of the car. Using the later DCD carb works easily with the linkage arm on top of a standard 600 rocker cover, as the stock arrangement pulls the linkage rod.
How is the linkage on top of the rocker cover set up on an Abarth so the the linkage rod pushes towards the passenger side? Or should I just rotate the linkage arm on the carb and be done with it?
Also, can anyone tell me if it matters much if I use a DCD3 or DCD7 carb? Were they both made as a 28/36, or is one a 28/36 and the other a 36/36? Can I get away with a 36/36 on the street (with 1050cc)?
Thanks,
Gil
