You need to adjust the automatic choke. Your choke may not be opening fully. There is a fast idle cam linked to the choke to keep the throttle open more until the engine is warm. The idle mixture screw is part 37 in the picture, but get the choke adjusted right first, and you may not have to adjust the mixture screw. See adjustment procedures at link beloe.

The firing order on an in-line four cylinder engine is 1-3-4-2, with cylinder 1 being the closest to the radiator in a rear wheel drive, or the closest cylinder to the alternator, power steering, AC pulleys for a transverse mounted engine. Please don't forget to rank this solution.

SOURCE: when installing a distributor on a 1985 nissian

With the valve cover off, turn the crank so the timing pointer is at 0. This is Top Dead Center. As you go past this point the exhaust valve should start to open. If it does then insert yout distributor so the rotor lines up with #1 plug location. If the intake starts to open, leave the distributor out and make 1 complete rotation of the crank until the pointer lines up to 0 again. As you go past TDC this time the exhaust should start to open. Now you can put your distributor in. The crankshaft makes 2 turns to every oine turn on the camshaft. Hope this helps.

How do I adjust the rocker arm bolts for the valve lash on a 1985 Nissan 720 pick up Z24 engine

Guys he has a Z24, Not KA24, Z24 for one, Is carbed and has older lifters and valves. They need to be tuned to spec within a certain specific limit and the cams must be rotated in certain positions when doing different valves, etc... Shouldnt take very long normally and its not a hard process but if you have a tick, you really should get it checked out. Btw, the Z24 engine's idle isnt controlled by ecu at all or else the carb wouldnt need an idle adjustment screw.

How do you adjust the carb on a 2.4 engine, 94 nissan pickup

You should have an air mixture and an idlig screw. The air mixture screw is set first untill engine idles evenly. then the idling screw is set untill the idling is as slow, being even, as possible. 800 to 850 RPM should do the trick. Then go back to air screw and FINELY adjust. Try to keep air filter onand make sure it is clean, new and not leaking air.
