  1. You are correct, sir. Checked and everything is seating properly. I checked my vacuum via the port that connects to the brake booster and my gauge is hopping all over the place, suggesting a vacuum leak somewhere. Manifold is tight and all the gaskets on the Carbs seem to seat properly. Since this is a new engine (~1,000miles), could it be needing a valve adjustment after break-in? Perhaps that's what's giving me those wonky readings.
  2. I don't think my OER's are setup like that; what Carbs is that diagram from? Everything seems to seat properly. The only thing I have yet to replace are these tiny aluminium gaskets sitting on the pump jets. I'll replace those and see if it still leaks.
  3. Floats are within spec. Even tried lowering them - no cigar
  4. Tried smaller pump nozzles - no change. I do notice that even with pump and motor off, there's still dripping from the nozzle into the barrels for a few minutes afterwards.
  5. Lowered it to 3psi - still drips. Could the size of the pump nozzle make a difference? I have one size smaller. I'll give that a shot and see if it does anything. My floats are all set at 29mm
  6. Ok, so I tested my needles and all of them seat properly. Ran pump with one unseated top at a time and all the seated ones remained shut and never leaked. My fuel pressure is still within spec and hasn't been an issue before...but what can I lower it to? 3psi?
  7. Yup, larger filter by pump and small right before regulator in engine bay. Hmm, wondering if maybe it was a batch of bad gas in there from my last fill up or maybe nasty junk in the gas tank that managed to get past the filters...if that's a thing. Thought the filters would keep stuff out, haha. Just odd that it all happen so suddenly and simultaneously throughout the Carbs - which is why I suspected fuel pressure first, especially since the car's health changed over it just sitting for a couple of hours after running healthy for several months. I'm no carb exper
  8. Just seems so sudden. Been running flawlessly for months, did a coffee run and on the way back problem occurred. Car was driven regularly throughout the week and hasn't sat for long. Odd that multiple needles have issues simultaneously out of the blue. Thinking maybe something in fuel line that spread across carbs and maybe clogged up something? Is that a thing?
  9. Hello fellow Z'ers, Recently started having an issue on my Z running really rich and I can see fuel dripping from the nozzle into the barrels. Car ran excellent for months; then suddenly went to start it and noticed my AFR in the 9's and noticed the drip. The motor is not stock; has a .495 lift and 290 duration, so keep that in mind. Idle Jets it ran - 65, but I also tried swapping in 62.5 and 60's and the AFR stayed the same. Mixture screws are 1.5 turns out. Fuel Pressure is right below 4psi (with 3.5 - 5psi spec) and was tested with two different gaug
  10. Ok, it's been a while since I gave an update, so here it goes! Every wire in the car, from front to back, has been redone, replaced or discarded. The car runs on what is needed. No heater, no fan controls, no radio, no antenna switch - not even the fuel light was spared. The car runs on only what's needed, nothing more and nothing less. The issue with the idle and pilot jets is resolved, too. Idles and runs on all six cylinders now! I'm not sure what did it, but I replaced my filter, cleaned my tank, cleaned out the carbs as best as I could and messed around with the idle mix
  11. So the Z no longer has electrical issues! I ended up ditching my current harness and re-modified a harness out of a 73 240z and used that. Works great and no longer giving me issues! Also installed some led bulbs in the car and some HID's while I was at it. I' currently facing an odd issue... During idle, Cyl4 and 5 don't fire. I checked for spark and compression - both give positive results. Turning the idle mixture screws don't do anything, either. Something get stuck, possibly? Under load I believe the engine runs on all six, but definitely not under idle (disconnected Cyl4 a
  12. Awesome! Did you paint those yourself? I have 45's
  13. Quick update: Bought a new harness and I'm going to strip the car down and re-do all the wiring. Figure I'm going to want to do that anyway. Hoping I find something along the way. Here's the sound of the car with the carbs better tuned (Getting a hang of it!)
  14. So been doing some more tinkering. To try and attempt diagnosing my electrical issues, I've reverted most of the electrics to stock: New Externally regulated alternator New voltage regulator New battery cables (x2) New OEM Fusible links With key set to "ON" - Alternator reads 12.20v Fusible Links read 12.20v Battery reads 12.23v As soon as I turn on my headlights, the volt gauge in the car drops to 0. Running lights, parking lights and dome light won't come on. Same effect occurs if I try to turn on the fan, use wipers or
  15. Moves just fine. Haven't had any issues with it. I got the carbs air synced (5kg/h), the floats set, the linkage synced and all the right jets (in theory) - now I need to adjust the idle mixture and accelerator pumps, if needed. Zedyone recommended an AFR kit that I recently got to help with mixture tuning, but I'm having some trouble with electronics at the moment. My voltage drops (dives) and shorts all accessories the moment I use any accessories, including head lights. Fan, headlights, windshield wipers, etc. All of these short out all the electrics. The only thing that does
