Sanchez Posted March 29, 2013 Share Posted March 29, 2013 Hey Hybridz. I got my Datsun 240z one year ago and have been trying to fix it myself but I am constantly being held back by the learning curves on this car. I learn better through experience not through reading, as most students do now-a-days. I am doing a Performance Restoration, but currently the car is mostly stock. My biggest issue is my SU carburators which I can get well tuned for about one drive then they fallout of tune again, this is probably due to my low vacuum at idle. I know I have sorted out the big problems with the car, but now I just have those little PITA problems adding up and causing this car to not run well. If you are one of those Z car experts on SU's or just other techinical areas in these cars drop me a line because I would be more than happy to make it worth your while if you could give me some pointers on a weekend or after I get out of school one day. I live in St. Louis city, just contact me, Thank you. Quote Link to comment Share on other sites More sharing options...
madkaw Posted March 29, 2013 Share Posted March 29, 2013 You might try Classic Z also. I think there is members there from your area. I work in ST.Louis sometimes and could help you out, but it will be a few weeks before I am in that area. I usually stay in Collinsville when I am there.

Xnke Posted April 1, 2013 Share Posted April 1, 2013 if your SU's aren't staying in tune, check them for leaking throttle shafts and sticking main jets. They're generally a set-and-forget type of carb, once they're setup and synced they stay that way for the next six months till it's time to check and sync them again.

str8pipez Posted April 2, 2013 Share Posted April 2, 2013 I don't know the SU, but I just re did the entire suspension on my 75, from bearings to camber plates and may be able to help in other areas. Where about in the city? I'm in Edwardsville but my business used to be in Mid Town near SLU. Quote Link to comment Share on other sites More sharing options...
Sanchez Posted April 2, 2013 Author Share Posted April 2, 2013 My SU's were rebuilt by Z Therapy just 4 Months ago so any air leaks would be in vacuum hoses or the balance tubes. Quote Link to comment Share on other sites More sharing options...
