first: keep the thread title short..
it's a bit annyoing if it's longer than your actual post.

second: post pics if you want others to make sound suggestions
if we know what you are working with, it's far easier to see what needs attention

third: make sure that braking and steering are far up your priority list,
looks and power are only nice if you know you can control the kart.

I bought this go kart yesterday and I’m breaking it down today. Should I do a weight reduction? Also there’s this big sprocket on it should I buy a smaller one?

You have an old beat up concessions kart (ya know, from minigolf amusement centers and the likes). That things is going to be really heavy unless you cut off a lot of stuff and make the frame into swiss cheese(Bugatti/Pontiac SD style). As it sits, it'll be very heavy but extremely durable. Unless you make it much lighter, keep that sprocket on. It may even need a jackshaft in addition.
But yeah, I would legitimately chop off whatever possible and drill holes to make it lighter.

Yes it had a lot of thick metal around it like a bumper car, I cut off the bolts and it all came off. I’m going to deal with the tires first, and figure out what to cut off and weld smaller angle iron to keep it strong. What size engine should I go with on here?

I have a 94cc ?

There’s a 212 predator at the pawnshop here in town I should go trade with some cash on top?

Actually it’s more than 212

I feel the sprocket is way to big! I’ll put the tires on after I’m done putting air in them and post a picture and you’ll see what I mean

I would not mess with the sprocket in any way until you know what size tyres you are going to use. The bigger you go, the bigger you need that sprocket to be to actually move you.

Just remember that anything bigger than a 212 would probably have a 1" output shaft. This means that clutches get a whole lot more expensive. You might even have to buy a 40 series TC to handle the larger engine. If cost is a factor in this build, stick to the 212.

that does not look like a concession kart.. that looks homemade..
(well made but at home not by a company.. you do not see too many professionally made karts with square tubing for good reasons ;))
modelled after some dirt racer I'd say (maybe dad was dirt racing and made that for his kiddo *shrugs*)

Anyhow, yes keep the large sprocket you will very likely need it.
the 212 should be a good enough engine for that thing, it looks a bit bulky and heavy, I agree,
but I doubt it actually is, the corners are very nicely bent with a bit of heat and a roller it seems
(the rear corner to me looks like the roller left the indentation.. and judging by that .. and the crisp corners of the tubes.. it's thin walled)
so overall not too heavy for a 212 IMHO
