Well, you have part of a moped. It's missing the front and rear fender, side covers, tail/brake light, but more importantly it's missing the entire air cleaner assembly, which is made up of a whole bunch of parts All those parts at the bottom of the diagram, below the black triangle on the right https://www.mopedjunkyard.com/TOMOS-A35-DELLORTO-Carb-Parts-Diagram-Ref-T7c_c_532.html

It has what looks like a Biturbo or similar exhaust, and the fact that the cylinder is aluminum instead of being painted black like the rest of the engine probably has a big bore kit. Hopefully nobody tried to do any homespun porting on it.

With a setup like that, the engine will need more fuel and air than the stock jetting and air cleaner can provide. You could get away with a pod type foam air filter that attaches directly to the carb. It would help to know how many cc the cylinder is. It might actually be stamped into the cylinder somewhere. You definitely need to remove the carb and take it apart. It is probably filthy inside, if the outside is any indication. The float needle is definitely leaking. It probably needs a new one. I use spray Berrymans B-12 or Gumout carb cleaner and guitar strings to clean out all the small passages. DON'T get carb cleaner in your eyes.

Check the jet and see what number it is. Stock jet should be a #53, but with a low restriction air filter, an expansion chamber exhaust, and possibly a big bore kit, it will need a larger jet. I would start with fixing that leak in the carburetor. It is never going to run right with it leaking like that. That might actually be most of what is wrong with it. It probably needs a little tuning, and there is no shortcut there. It is done by trial and error. Just think of it as a fun learning experience.
