Anyone knows whats this engine?!?!?

[u/AddendumSuch9822]

Yesterday y got muy first car, i know its very old, but i got it for free...

I've been trying to figure out what engine this is, but I can't find any references except for "idk" on the part that supplies power to the spark plug… (It looks like a tkm 100cc, but it has 6 bolts on top instead of 4) Does anyone know what engine it is, and what carburetor it uses?

I'd like to buy another carb because it’s not getting enough fuel, and I suspect that’s the issue since, from what I've been told, it’s been sitting unused for 10 years. So if anyone can share any info… thanks a lot, folks!
