yes 72. It ran well until the points distributor went out, so I replaced with 280zx. I'm not exactly sure whether it is from a 79 or 80, I will have to ask the seller on ebay who I bought it from. I think its 79. The car was sitting for like 6 months until I got the new dizzy installed and running. So I know I need to tune/adjust my carbs, maybe rebuild them. Also, the previous owner took off the throttle control valve on the intake manifold, and disconnected the servo diaphragm. He actually bent and grinded the inlet (to the servo diaphragm) to make the sway bar fit. And the Control Valve manifold connection is now connected to the A.B. valve connector. These terms are from the Chilton manual, 2-14 Fig. 29.

I recently installed the 280zx electronic distributor. I finally got it running the other day, and got the timing about right. Then I sprayed the hell out of the carb intakes with carb cleaner and let them sit for a while. It runs with the choke fully on (also set to "winter"), but has really low RPM, around 500. It will start, go to around 500, then slowly drop. Also, yesterday after I had started it a few times over a couple minutes I looked and the temp gauge was way over the limit. But the engine was barely hot. Anybody know what the issue(s) could be?

Yeah i did install the correct mounting base, I bought a complete refurbished kit off of ebay, came with the correct mounting base. I had to stop testing today though because my neighbor couldnt stand the noise. Really lame. Where is your distributor adjusted to, relative to its range of motion? because mine is all the way clockwise.

ok, i got the car running finally. I had to move all the plugs on the distributor cap one position ccw, because the other way had the timing way too advanced. But now the distributor is rotated all the way clockwise (fully advanced) and it is still slightly retarded, but only barely. the car runs, but im pretty sure it needs a little more advance. ive read that it need about 8 degrees BTDC at idle, but i cant advance the distributor any more. anyone else had this problem?

Yeah I kinda figured that. Just making sure. I can't figure this out, is it normally this hard to get the timing right?

Ok, I've made SURE that the firing order is right. I hooked up a timing light, and its getting spark, but my battery is dying now so I can't really keep testing at the moment. I turned the engine over for Cyl. 1 to be at TDC, and the distributor seems about at the right spot. I'm thinking that maybe it is a faulty E12-80. If it was defective, would I be getting any spark at all? I had the terminals mixed up in the beginning, and turned it over, would that have fried it? I have an extra module that I could use, but I want to be sure its that. I can hear it igniting sometimes, but its definitly wrong timing.

I just put a remanufactured 280zx dizzy on my 72 240Z. It seems like everything is fine, but I haven't tightened the adjusting bolt yet because I want to get the timing right. When I turned it over, it sounded like a preignition or pop inside engine, and then today when trying again, it just backfired hella loud. I'm thinking its just not timed right? I was going to take #1 plug out and make sure its TDC but didn't have the tool with me. Any ideas?
