Temperature of 95-100 degrees for the fan coming on doesn't sound like a problem to me. Was the thermostat replaced? New thermostats usually allow the engine to run hotter than an older, not-fully-closing thermostat.

Well... you can change whichever engine component you like but the problem won't be solved. Personally, I wouldn't call it a problem; sth like a fact suits it better. The fact is that these old engines with carbs do not behave normally when cold. I know it from my Duna. My advice is that you leave the choke on somewhere in the middle of its way after you have started your engine and do not drive the car immediately. Give the engine some time to rev and the oil to warm up. Also, when cold, do not accelerate hard because the carb will be overfed with gas resulting in that stalling issues you mention (personally, I never accelerate hard, at least not without shifting down because the car never responds [bloody carb] and I end up going with less km/h than before). I believe that what I just told you is common sense. Do not expect an old car to behave like a brand new one equipped with all the electronics designed to make our lives better. You should learn to live with it.

Afraid it doesn't have a carb or manual choke, this is my third FIAT Uno with a FIRE engine with SPi, never had any problems like it before. Been taking part of my old crashed one to try solve problems, so far no luck, oh well, the search goes on. Will let you all know how i solve it if and when i do.
Just on the off chance, was thinking of taking out the old engine so i could strip it down and rebuild it, play around with it, will get more experience with that than i do on my engineering degree! But wondered if anyone had taken the whole thing out including all systems like fuel/cooling etc and and wondered what are the chances of me actually being able to do it?
One more thing, anyone know where i could get gaskets for the fuel injector unit, coz uno garages don't seem to sell them seperate from the spacer between the unit and inlet manifold? Don't particularly want to spend £30 just to get 2 gaskets.
Cheers

I have to agree with Kyriakos to some extent... but it also helps if you can drive a few other Unos of similar spec to decide what is 'normal' behaviour.
As for the gaskets, I'd clean the old ones with meths and use Loctite 518 Master Gasket. I wrote about this stuff a moment ago, I love it. It's translucent red, not made of silicones, and it only sets when there is no air (between surfaces). It sets quite hard, so it's not affected by oil or petrol. It's not particularly cheap, and your best bet for finding it is probably an industrial bearing shop (they will carry the other Loctite products as well, so make sure you get the 518!). It comes in a handy syringe (ideal for precisely applying a small bead) or in a larger tube (not so easy to use).
I was first introduced to Master Gasket about six years ago by a truck-racing mechanic (we were refitting an SU carb to my Austin Princess, the silicone sealant having gone all gooey). I didn't take much notice at the time, but re-discovered Master Gasket a couple of years ago, and I will never use silicone sealant again unless it was originally used (e.g. on the FIRE sump).
Master Gasket will dissolve easily in oil/petrol if not set (remembering that it doesn't set unless trapped between surfaces). This is good, because it means that there are no squashed-out slugs of rubbery silicones to travel around the engine and take up residence in the oil pump.
I'd just like to point out that I have no connection with Loctite (r), and also, Loctite make a whole load of silicone sealants which I won't use.
