    Okay so my truck was having issues starting, and the engine would crank but not fully start and then it sounded like the starter somewhat ******* out and slowed down and wouldn't make a noise if I tried starting it again. Idiot me went thinking it was my starter that needed fixing, but the truck would run strong otherwise. The shop then proceeded to tell me the truck was fine at 10 this morning, then told my dad it needed a full rebuild when he picked it up at noon. One of the spark plugs wasn't even plugged in so once I got that taken care of it started right up and idled fine. I shut it off and started it again after 10-20 minutes to see if it still could, and now it will idle at extremely low RPMs and shake the whole **** truck until it just shuts off. Wtf did they do to me? Cause seriously besides starting the truck ran amazingly, and now it's better at starting but now won't idle, and when I throw it in first and try to go for the first 1500 or so RPM (no tach just guessing) has almost no power and I have to floor it to keep it from stalling out. Wtf. any help please

    Check and be sure all of the sparking plug wires is hooked to their proper terminals and the proper plug.
    Check the timing.
    Be sure all of the vacuum hoses/lines are hooked to their perspective components.

    I have a 1984 Mazda B2000 as well. When I got the truck it had one vacuum line on it. And I am pretty sure it was not hooked up right.
    It ran from the valve cover over to the spark advance. I got it running. But it had a strange rattling sound from inside the engine.
    I had to replace the head gasket, and to my surprise I found the noise. Someone had replaced the timing chain. But not the gears.
    And when they changed the chain out they left it inside the oil pan. Hey I can not make this **** up. So I put all new head gasket timing gears and chain tentioner. Even went as far as to put a new oil pump and new chain as well. At present it runs but not well. As I said before it only had the one vacuum line on it. And it was not right. So if anyone has a diagram that old idiot like me can read Please let me know.

    Thanks for the reply ! That is for B2200. I got a B2000 it is different. What is hard is there are so many parts under the hood that hook up to vacuum lines. There's one for the spark advance and one perhaps more for a choke. And there is dozens more that have lines running to them.
    But I have no idea as to what they are. Then you have , I know of two vacuum source on the manifold. And there may be more. I am going to need something with a lot of pictures. But thanks anyway.

    First thing I would do is plug any vacuum sources on the carb and manifold. The line from the vacuum advance on the distributer goes to a port about 1/2 way up on the carb. That should get it running better for you until you can find a diagram
