Anyone know how to synchronize 72 240Z carbs? What do I need for tools, etc.? Where can I get these tools? How much would it cost to get them synchronized by a mechanic of Nissan/Datsun cars? Any other information I should know before doing it myself?

I was at a Z shop on Tuesday afternoon. Requested this exact information. I was quoted $112.50 to start. I explained that I just rebuilt the carbs and needed it done. Was told I need to wait for three days before I could get it in.

Hope that helps.

I would avoid having anyone else do it.. I had a Z specialist do mine while it was in for something else, and I got back a car that wouldn't maintain an idle. I had to re-do it on the way home.

www.ztherapy.com has a video for $15 that shows you how to do it, or just go by the suggestions you get on this board. It's really pretty basic. As far as tools go you can get a 'syncrotester' ($28 from Motorsports, probably less elsewhere) and the only other thing you need is a screwdriver.

I would recommend you spend $45.00 on a good Mercury Manometer from your local motor cycle shop. They are MUCH more accurate than the Uni-Sync.

Before syncing my carbs I would like to set the float levels correctly. I have read that the fuel level should be visible just below the top of the jet nozzle with the suction chamber and piston removed, mine are not even close. What is the easiest and most accurate way to set the float levels without the use of special tools? I have the float chamber covers off now and need a little help here Thanks. P.S. I'm using standard needles and have the black foam floats.
