Matt, Dimensionally they look identical. My understanding is that the spring rate is doubled. Keith gave us a part number and his source, the problem was that you had to have a minimum order of $40. He bought 30 of the springs and I suspect is selling them on his Yahoo store. They were about $1.40 each I want to say? Pretty lively difference I'd say.

Only a hole down the bore. I wonder if it replaces the hypojet but without the hypo?

Leon, What is this? It looks like a pump jet but shorter. Keith put them in my package and I would imagine yours but all he mentioned was the O5 tube.

Well, it wouldn't run with the O5 tubes. It would start and run badly but no coaxing of the throttle would get me moving at all. But when I put the original tuning-day configuration back in with the new accelerator pump springs things went back to running like it did at the tuning day and on the way home, with one strong exception. When I jump into the throttle from anywhere, the A:F ratio goes to 12.5:1 and stays put. It loves the springs! In fact, if I do go with my plan, to sell these rare beasts to some Maserati, Ferrari, Morgan restoration guy, I will buy 45DCOE 152's and replace the springs!

Dry as a bone here. Literally I think. I hooked up my fuel pump differently. I ran a 12 gauge wire directly to the coil with a 20amp fuse just before it connects to the coil. Increased my fuel pressure to 3psi. I took it for a spin and it acts differently. I would imagine partly because I eliminated the MSD box. It probably was covering for some problem. I have to do that EDIS! By the way, Leon, why did you do two different mounts for your EDIS stuff? You have the box on one aluminum plate and the coil pack on another. Are you avoiding interference? It seems everything would fit on that one mount... Waiting on the package from Keith to start tearing in to things. I suppose I could do two carbs but...

So, I have two wiring diagrams. One is the FSM which I have two copies of. It seems that according to the FSM, there are only two wires at the coil. One comes from the distributor and goes to the negative side. It gets no more detailed than that, which is frustrating. On the laminated wiring diagram I got off of EBay, I have a green/white wire going to the coil from the tach. That doesn't jive with reality. It indicates it is for a '72 -'73 but that configuration seems to me to be from an earlier car. There are 4 wires coming out of the harness right next to the coil. Two appear to be black with a white stripe. One is all black, one is black with either an off white or faded yellow stripe. The car runs. It has one of the black with white wires which I found to have a 12V attached to the + lug of the coil and the single wire from the distributor hooked to the - lug of the coil. So, the other three wires are hanging in the breeze. I suspect one will give me a tach. I wonder what the others are for? So which of these goes to the tach?

I'm up and running. Turns out my MSD was eliminated by the recent install of the bladed MSA fusebox. So, I wired it up stock. 8)

Not a Z but historical...

Another at speed...

Leon, It just so happens that I have two pump springs and two carbs worth of O5 tubes. Maybe you could send me one set of yours? 8O Lotus guy, Senna did pretty well today (last night) in India though...

:paranoid:

Thanks Stanley... But mine's not stock. It is using an RX7 pump that worked fine before I undid a hack and put in a MSA bladed fuse box...

Ok, that's frustrating. I ran a 12 gauge wire from the fuel pump to the + side of the coil with a 20amp fuse just before the coil. Nada... Ground is local to the pump.

Spitz, You may be in luck anyway. You are in the Bay Area so you can just contact Keith directly and go to his house. It isn't that far and he can show you how to clock them correctly and directly observe your result...

True dat! You gotta be approved before you post. Contact Keith directly using the email I gave you in the PM.

Perfect Matt! Thanks!

Thanks Leon. I will probably be using a trigger wheel from a link I found on Rebello' site. Unless Mark wants to make his own. I actually have a question about the stock tach with EDIS. Does it work?

So I let Keith know that we had three volunteers and this was his response: Three fools, scratch that, volunteers is fine. My son strongly urged me to make sure the bubble pumping effect works for other carburetors before releasing my e-tube paper so I need the data. -Keith Franck You will find that Keith has a very healthy sense of humor! Contact him as soon as you can. Identify that you are a Z car Mikuni guy and that Rob and Leon told you to contact him. He will send you what you need to install and tell you what to do. You can ask questions directly on Side_draft Central or here. Leon for sure, and I have a pretty good working understanding of these things. Good luck! Hope these things work as well for you as they work on the Webers! By the way, I know Steve in Houston has an A:F ratio set up. If Steve in Indiana doesn't, I will show you some pictures of my set up here. It isn't that expensive. Prices for Innovate set-ups keep dropping. As you can see, I welded the bung to the inboard side of the header. I ran the wiring across the top of the firewall on the engine side and entered the cockpit through the passenger side. The rest, you can see. I wanted to be able to hide it so everything looks original.

You're in Steve... That makes three. We've got Bill (Silverstreak) Steve (Madkaw) Steve (Steve91tt). I will send you a PM Steve in Houston. I already sent one to the Madkaw! Silverstreak is local to Keith and loaned him one of his Mikunis to make this possible. If you haven't already, join Sidedraft Central on Yahoo Groups. Keith tends to communicate with a mix of public group discussion and personal emails. It would be great if you guys were to publically discuss what results you get here too.... Except Silverstreak, he doesn't post anything anywhere. 8)

Thx...

So far so good. But I will let him know...

Pm sent!

Close-up...

I currently have an electric fan on my L24 '73 with an aluminum crossflow radiator. I have a new 280Z fan and fan clutch that I bought for my 280Z but never used. Will it bolt up?

You know, we can't have it both ways. We can't be telling people with an indignant undertone to 'do a search' and then complain that they are replying to 7 year old threads. If you think about it, digging this up is valid since when the thread was started, using a Turbo AFM on a NA car was problematic at best. Now, with some of the programmable fuel injection available, it might be one of the hot tickets... Just sayin'...
