Suzuki: 87 suzuki samurai carb problem, o reilly auto parts, o reilly auto

Question
QUESTION: I bought a 87 samurai. when i got it it was knocking pretty bad. It was running and was idling fine apart from the knocking. i got another motor that a friend had taken out of his(running) and swapped it out.  Now it will not idle. I crank it up and it will rev up then die.  If i rev it up to 2k rpm's it will stay running. I have rebuilt the carb with a kit from O'reilly auto parts and checked the float twice by taking it apart. Also when i do get it to stay running(2k rpm) if i look in the carb it is just dumping fuel in it. i thought maybe it was the needle and seat for the float and put the old one back in it but it is still doing it.

ANSWER: Have you checked to see that the intake manifold is from the same year vehicle, and looked at a factory manual to see that all the hoses/wires are correctly hooked up, and actually operating as originally designed?  Most of the time, it's a vacuum hose problem, of a crummy wire connection.

QUESTION: First of all thanks for the help. Secondly. I checked to make sure the intake was the right one for the motor. It checked out ok. I then went and bought some vacuum hose and changed out all the vacuum hoses. Now it will idle until the choke opens up and it revs up to 3k rpm's. I try to idle it down with the idle screw and at about 1600rpm's it gets very sporadic and slowly dies. While this is happening it is running very rich and just pouring the gas in on it. I have taken the carb apart twice and adjusted the float but it seems to still be dumping to much fuel.  Also if I unhook the three connectors going to the carb it idles better and tends to not cut off until about 1200 rpm's.

Answer
We have a problem.  the issue is that unless I know what device the connector actuates, I can't tell you what is what.

Get a factory repair manual and read the fuel section.  Then go start diagnosis.  It's what I had to do to learn this stuff, and you should do it too.

I'm not trying to be dismissive, I'm trying to arm you with the things you need to keep your vehicle working.
