can it be done easily? is there any advantage over either?
also, can a manual choke car be converted to auto choke?
Unless you are thinking of dropping in a 1242cc Punto Engine, I wouldn't have thought it was worth converting from carb to injection.
The carb FIRE engines apparently feel 'crisper' to drive (I wouldn't know as I've only ever had carb Unos!), but that's probably more to do with the restrictions of emissions and a catalytic converter on the SPI models.
I also agree with Dave. Most auto chokes became problematic over time, mainly in that they didn't shut off early enough causing the carb to run rich. Also, the Uno was never fitted with an auto choke as far as I'm aware, meaning that you'd have to adapt a system from another car. Not a good idea.
However, converting to injection can be done. You'd be best off finding another complete Uno with injection (quite a few rusted out mk2's with good mechanics available for peanuts), then transfer all the injection equipment to your carb Uno. You'd probably need to swap the engine bay wiring loom over at least, plus fit a cat exhaust, injection fuel tank and also things like fuel pumps/ distributors/ coils/ sensors.
I was looking into this when I was considering putting a 1242cc Punto engine into mine. Otherwise I would prefer my carb over injection any day. Much more simple, easier to work on and simply less hassle with less to go wrong.
Plus the carb models aren't stifled by the cat and ECU like the injection models were, so tend to feel a little more zippy and responsive to drive.
My advice would be to stick with the carb!
