Carburettor, E carburettor, injection with 2 beat or 4 beat 50 ccm confused?

Hello , would like to buy me again a scooter , had my 2 clock Piaggio Zip sold back then unfortunately where was not foreseeable that the gasoline prices would rise sometimes so strongly , and yes now in the weather I miss that also something . Now poses for me the question what a technique ? I only know the one of my Zip carburettor 2 clock which was very well pulled but also thirsty . Read a lot with the younger and new , 2 or 4 clock with E carburettor or injector . I would to 1000 E uro to spend for a used . Or like here an almost new for 1550 euro .https://www.ebay-kleinanzeigen.de/…/2108353415-305-17135 If I take now a 2 clock with injection consumes it nevertheless not much or ? Does it hang better on the gas than a 4 clock with zb E carburetor ? The Kymco is a 4 clock with E carburetor does what ? I would probably prefer 4 clocks this time because of the consumption and because I find they are smoother running . But I have never driven . Bas I can teln , but the desire to do it has also decreased somewhat with the age . Therefore you would certainly advise me to a brand scooter , which I then can then also bring to the workshop times to wait . Must say I would for the time being also do without a car , would even if I would get me again a 2 clock would still save some even if this is more thirsty . Is 4 clock with injection more expensive if something is defective ?
