Maybe you need to reset the level on the float.
Also, after you do that, use one of these

to adjust the idle/air mixture screw.
You don't have to buy one, but someone locally will have a similar machine for checking CO in the exhaust.

First, of course, you have to check for codes and do a compression test.

Once you get the cars dialed-in (compression, leaks, bearings, alignment, brakes) swap in new rubber and glass, you've got something which should last for years!

Now, you want to read about carburetors?
Check this out; there's a pretty good explanation of a carb which is a tad bit more complicated than your Aisin here:

So if you read that whole album, it should be easy to fix your carb.
Don't forget: nothing gets done until after the compression test, right?

Cheers, mate.
