WHAT CARB FOR FIAT DOHC / JAKI GAŹNIK DO FIATA DOHC
[English &. Polish ]

Weber IDF
Weber IDF is one of the best and most popular sports carburettors. Built by the Italian company Weber from Bologna. Currently, the company does not exist and its traditions are continued and developed by RedLine Weber from Spain.

(Side draft Weber DOCE was not mounted on 124 and 131 models due to too little space. They were used on front wheel drive models like Ritmo, where there was ample space.)
Barrel size is a matter of preference. Some will go for size 40, some for 44 and some for 48. No matter which one you want you have to have two different carbs: one left and one right.
Cold Start.
The original setup was with cold start (choke). Later the cold start setup became less popular due to problems it an cause. In these models the external cold start mechanism is not present ( just blanked off by a screw on plate).

In fact this is a half measure and does not cure the clogging problem. There is a set of jets beneath the blank off plate an they still do have a tendency to clog.
