I am working on a 1974 260Z and about to the point of FINALLY driving it! I am looking for a good reference on someone who knows and can work on these dual carborators for this car, one of the carborators is pooring gas and needs rebuild/tuned, anyone who can help, please advise soon, thanks!!

Nobody seems to like those flat top SUs but you can get kits from Victoria British as well as a book on them. it's not rocket science. Simpler than a Holley or Rochester. If you can find a deal on ebay for the early SUs you can bolt them on your same manifold.

 

Do a simple rebuild and you will know pretty much all you need to know about them. They are pretty simple in the carb world. Not like messing with a quadrajet.

If it'ss dumping gas, my thoughts is that you have a sticky float, or a needle that is just dirty. Not a big deal. Rebuild, and you should be just fine. Unless you have done a lot of work to the rest of the car, I doubt you would need any different parts like jets.

 

Thanks for the input....I will try that.

 

Thanks.....I will make note of that company in the event it gets to that point.....take care!
