  1. Yeah, I am running stock NGK plugs gapped to .028. I mean, it has to be fuel, I pull the plugs, black and sooty means rich condition, they smell like fuel, it doesn't smoke at all.... And exactly Tony, I would surmise fuel in any other motor, but I have had multiple people tune these carbs and each one has extensive experience with SU's and Z's. I guess maybe just try to go even leaner than before and see what happens. Thanks for the input guys, I will keep updating this thread until I get this figured out.
  2. I've recently replaced the plugs, plug wires, cap, rotor, coil, etc. haha, I'm so at a loss here.
  3. No 3 plugs are fouled, it's all of them untill the car doesn't run.
  4. First off I've built many 240sx's, rebuilt many motors, tuned many cars, used to work on racecars, etc. I would consider myself to be very knowledgeable in the mechanical department, but DAMN I'm stumped, and I have never dealt with these motors before, but it seems pretty straight forward. L26, E88 head, Round top SU's, stock exhaust, etc. Well when I first got the car, I retuned the carbs, and the car ran great for 200 miles, then the plugs fouled. They were black a sooty, a sign of running rich, so I retuned the carbs AGAIN, and they were pretty close to spot on, then took it to a local Datsun guy who used to race these cars who made sure that the Carbs were working top notch. He made a few adjustments, but they were pretty close. 200 miles later, fouled plugs again, same thing. I had yet to check the timing, so I put a timing light on it and it was at perfect TDC on the timing marker. Which I believe is the 2nd notch from the top, so I advanced it.(I think, I can't find any information on advancing/retarding in reference to the timing marker thingy) to the 2nd mark from the bottom, so I'm guessing that's around 15* BTDC advanced. I retuned the carbs immediately afterwards, and now it still feels slow, and sounds like it's missing a little under full throttle. So I'm just asking for some feedback on what this could be, what I could be doing wrong? What I should be doing? Etc, Criticism is incouraged! Poke holes in my story, poke holes in my mechanics, I really don't care, I can handle it, I would just like some insight.
  5. I replaced all the fuses and....nothing. Time to use my multimeter.
  6. Sweet! Good info on the fuses, I'll go ahead and replace them all to be sure. And order new fuseable links to be in the safe zone. I also found a mice nest behind my trim right under the guages, looks to be old, but I'll pull the dash out and go over all wiring because that could very well be a problem too.
  7. So I recently just picked up a '74 260z with some wiring problems maybe? My symptoms are as follows: -Dash lights do not come on with lights, NONE. -RPM gauge decides when it wants to work, most of the time it does. -Other gauges such as oil pressure, water temp. etc. In the middle of the dash do not work whatsoever. I checked my fuses on the passenger side kick panel, none of the fuses appear to be blown(visually), I also checked the two fuseable links in the engine bay and both those are visually okay. Has anyone had similar issues? Just trying to feel. I frequent car forums, and I do know how to search, I've searched, and it just doesn't seem that anything is as precise or direct. Thanks in advance!
