Toyota carburetor

i made the mistake of running some carburetor cleaner through my 83 toyota's carb. It was running okay before this except the idle had stuck on high yesterday while I was out. So, like an idiot, I tried to clean it a little.

Turns out that previous owners had probably been adjusting the carb for years to compensate for crud buildup, and now the thing barely runs since I removed a bit of it. It idles so slowly I have to keep feathering the gas to keep it running, and it's idling very rough.

I only know enough about cars to be a little dangerous, and I'm very poor. I know the carb needs some adjustment now, and I should finish cleaning the goo out of it, but I'm unsure what adjustments to make to which screws, and how best to clean the carb (not allowed to work on cars here, so I can't crawl under it, take the carb off, etc.). Should I turn the idle up? Is that clockwise? What about choke? Where are the adjustments on a Toyota carb? I've always had American vehicles.

I can spend all of about $30 on it. I'm disabled, and I just don't have the money for a shop. Any helpful information, websites, etc. would be very welcome. I am entirely on my own with this old thing.

Thanks guys.
  • This may not be the kind of thing to tinker with. If you adjust it incorrectly you can end up with burnt valves and seats or even cylinder damage. Adjusting it wrong the other direction can lead to damaged emissions equip or washed down cyl walls.
    I would get a shop to adjust it per the original specs. It will run at its best and be reliable.
    If you go at it yourself you at least need a tach and a vacuum gauge. Then study up on how to do it.

    Good luck,
