From experience with a 1.3 Carb - yeah, it's simple to fix. I used to maintain my carb myself.

But a 1.6 EFI will give you similar fuel economy (the 1.3 is better on the highway, but only if it's clean), less headache, more power, etcetera, etcetera, etcetera... but that's given that you keep it well-maintained and have the sensors cleaned every now and then.
