Fiat Uno cold start problem

Hey everyone,

I have a 1 litre 1994 fiat uno (with a FIRE engine) and am having problems with it whilst the engine is cold. The best way i can describe the problem is that it is like having a car with a manual choke, and not using the choke at all. While the engine is cold, I have to keep the revs up to prevent the engine cutting out. Once it has warmed up, i have no problems at all.

I have already replaced spark plugs, HT leads, rotor and and the distributor cap. These all needed doing anyway so it seemed a good place to start.

I wonder if anyone else has had this problem and could perhaps suggest what is most likely to be causing the problem.

Any help would be much appreciated.

Thanks

Ben

If I remember correctly, the Unos of this period were still carb based but did have a whole load of air correction and ignition advance tubing connections driven off the manifold via thermal valves connected to the water/engine block temperature. These used to have a habit of cracking/splitting and thus allowing air in and changing the engine operating parameters.

Suggest you carefully check all small bore rubber hoses attached to the carb, distributor and other places.
