Not really a major issue, as the 60s has always done this, but I'm sure "from factory" these issues weren't with it, so ideally I'd like to get it rectified and get her running pretty much perfectly.
The car is: Fiat Uno (Mk2) 60s 1108cc, with manual choke and carb.
First "problem" is when warm, and running at normal idle speed (the car has a manual choke). Inside the car it feels relatively smooth, although perhaps a bit "lumpy", however outside, you can here the exhaust kind of "coughing", and almost popping, as if it's running too rich. Ultimately not a major issue, and perhaps I'm expecting it to be smoother than it was always meant to be?
Second "problem" is warm/hot starting. On a cold day, or from cold, she needs some choke, a quick flick of the key and she fires up. You barely hear the starter motor as she's so quick at catching. But if you drive her up to normal temps, leave her for about 10 mins parked, and come back to her, she won't fire, unless you dab the accelerator while turning the engine over, then she'll fire up but for the first 15 seconds or so she feels quite rough, this clears and she drives normally afterwards. Leave her for a shorter time and she'll fire straight away. Leave her until she's cold again, and she'll fire straight away.
Do you think the two are connected. Slightly rough idleing, and poor starting when hot?
Are there any modules or parts that can easily be replaced, which might help with this.
She has new:
Plugs,
Leads,
Distrubutor Cap,
Distributor Rotor Arm,
and been serviced about 3 months ago.
I'm thinking the vacuum advance, on the top of the distributor? Or is there another module (ignition module) to look out for?
Once again any help would be great.
