I opened up my 1400 nissan bakkies carburetor to service it and i am not sure where all the differentjets must go


In general there are fewer ways to adjust the newer carbs than the vintage carbs of the past. Often the vacuum at low idle is the problem and you should check a vacuum port on the intake with a Vacuum gauge. Sometimes an EGR valve does not shut completely and the engine struggles at idle. If you find that vacuum is adequate, you can adjust the air mixture screws to provide the highest vacuum reading and then crank them in until the vacuum falls less than 1 inch. It might be beneficial to run the engine and spray a water mist from a hand powered spray bottle around the seams of the intake and carburetor. Also spray any vacuum solenoids or lines. You will notice a change in RPM if there is a leak. You may have a fuelpump problem A clogged fuel filter or low pressure can affect how the caricon1.png idles. Please rate my info.

The battery light turns on and then when then when i put my stick shift on neutral i turns off


You have to get the idle adjusted right on the carburetor and at the throttle controls on the carburetor. Nissan varied the idle controls a lot from year to year. Your '85 might be pretty simple and straight forward. I might be able to help you through it. You would want the engine running with the carburetor exposed-so with the engine off, take off the air breather assembly. Yes, they are complicated little pieces to get off, but has to be entirely removed. There will be one vacuum connection to pull off from the bottom of the assembly. This is manifold vacuum, so you don't want to leave it open, will make the engine run funny-rough- close it with a golf tee, or a screw or bolt that fits in the hose end tight. Check for other vacuum lines, may be other small lines that are actually fresh air vents. If there is an electrical connector to the breather assembly, just unplug it at the engine. That would be an air temperature sensor , if so equipped. Now you can see your carburetor controls, look for an idle speed screw that you can turn in to raise the idle, raising the throttle plate raises the idle.

Engine idels at 3000 rpm after replacing carb and vacuume lines with new parts.


There should be an idle speed adjustment screw near where the throttle linkage connects to the carburetor. Turn it CCW a number of turns until the speed drops down. Make sure the choke has completely released before making this adjustment. Hope this helps!
