Getting the timing right

Alright plain and simple question howdo i change the position the dizzy is in im using a 76 dizzy on a 82 zx engine.

 

Ive read that you must lift the dizzy slightly so you can spin it but this makes no sense becuase the notch wont be engaged. Is this how it normally works is the dizzy supposed to be free ontop of the notch for a second so i can get the timing right?

If you want to mess with timing on the dizzy, why not just loosen the bolt on the advance plate and rotate the dizzy and tighten. This is going off of the first gen Z car so I don't know if the ZX had a advance adjust ment on the dizzy.

 

I will post pics later since I have both NA and turbo dizzy out of the car right now. BTW is it NA or turboed?

Oh, OK. I didn't read it clearly. Do what I said in my last post. The pics I'll post later will help.

 

On the 280z engine, there are 2 ways to advance or retard the spark. On the bottom of the dizzy is a plate bolted to it, adjustment bolt should be on the front side of the dizzy. I think it only gives you 15 degrees to adjust. If you need to adjust it even more than what is allowed, there is a tiny bolt on the under side that you can mess with for another 15 degrees, but if you need to adjust that much than I think you have the plug wires in the wrong order or the dizzy/wire order 180'ed.

 

Try to clean the area under the dizzy, I didn't even know it was there untill I took it out (it was caked with dirt and oil).

Most likely you did, but I'm asking anyways. Did you check the rotor and cap? And also the spark plus to see if they were fouled?

 

Another problem area is the battery terminals and the connection to the starter. Also check the connection to the AFM I have found that many people with L28's and had problems starting had this as one of the problems. (disconnect the battery) unplug the connection, clean it (both sides) with a wire brush and put a little bit of dielectric grease on each pin, and plug it back it.

 

If it was running before than I don't see anything that would cause it to not work other than someone messing with it and/or time.

Get a manual. Set the wires to the correct firing order. Try to start. If it doesn't start but kicks like the timing is way off, then remove the oil pump, drop the distributor drive out, rotate it appropriately, put it back in and try again. Every time I pull the timing cover off I always screw this up and end up pulling the oil pump off again to get everything timed so that the engine will run.

AFM i will check as for manual

 

The chilton had the wrong order according to

Could it be that the zx and the z engine have different mounts on the dist

 

The z is much more cocked than the zx and points the to the thermo almost

What do you mean the wrong order? That is the correct order.

Yeah having the AFM pluged in makes a huge difference. I dont see anyway that it started without it the AFM pluged in...:icon52:
