  1. I hope all is well to all our friends in Dallas. It ran 2 blocks south of @jfa.series1 Keep him and his better half in your prayers.
  2. Oct 20th, 1969 First ad for 432 in Japanese newspaper, thanks to @HS30-H: Later that same day: Oct. 20th, 1969....Big Loop!
  3. Sounds like air leaks in the intake manifold somewhere and maybe floats or fuel needle valves sticking.
  4. Oct. 18. Press Preview in Ginza, Tokyo, Japan. thanks to @HS30-H
  5. https://translate.google.ca/translate?sl=ja&tl=en&u=http%3A%2F%2Fwww.jmiu-nissan.com%2Fhistory.html
  6. Some of the early Z's did have plastic fan blades but they said FairladyZ on the side. 🙂 The line worker's had hats in the early photos but helmets later.
  7. Testing Begins! Another Video from @kats. Music: 1969 Iggy Pop and the Stooges RoadTestingInUSA.mp4
  8. Meanwhile, back in the factory, production is in full swing. 100Z's made in Oct. 1969:
  9. Sorry I missed Oct 10th. BIG DAY. @kats Here are some videos of arrival of first Z's from Kats (BIG THANKS!) . Music: "These Days" Nico and Jackson Brown USAArrival&Prep.mp4
  10. It may go lean as the rpms rise (theoretical) but practically on Webers it mostly just leans all of the WOT run so I can't say on your M's The pilot/idle jet is also too large, You may want to adjust after you sort the Main. What is your idle a/f and cruise at 60mph a/f? Aim for 13 for smooth idle, aim for 14.5 for clean idle Aim for 14.5 for norm cruise. Aim for 16 for fuel efficient cruise.

  12. copper backing and shot of compressed air to cool?
  13. Actually you are very lucky to drive with a/f of 9 and 10! JobBill is spot on!
  14. Differences can be in body casting and possible changes to machining and components. Here are some of the key items that can change: 1. progression hole size, quantity, location 2. throttle plate angle 3. accelerator pump excursion probably others that I am forgetting. For triple applications, it is important that all 3 carbs are the same.

  16. @Mike Posted this great table: Here is what you need for starting: So your main is too large,and pilot is too large. Reducing these will raise your A/F
  17. The vent is the big fat tube (bottom one) below. It goes to the 3 way valve next to your coil on the inner fender. See the red cap on the 3 way valve in the second picture below.
  18. The only vacuum line needed is the one that provides vacuum to the brake booster. You have a 1973 or 74 manifold so you can remove most parts on it and ensure that all holes are plugged. No need to plug water holes. You will need a way to hook up the throttle return springs. You will also need a low pressure fuel source ~3 to 4psi. Here is a minimalist application of SU's on an L28
  19. The reverse switch is the brass object near the middle bottom.
  20. Interesting: 240/260Z/280Z have same Mikuni Settings for 40mm's. Weber and Mikuni are close for same choke:
