is it normal for the idle to go higher by about 250 rpms after the car has warm up to operating conditions ? starts and idles at about 700rpms then it goes to about 950 rpms after warm up .

Here is the issue. I have a 260z that has headers and many of the original pollution control items have been removed. The carbs have been rebuilt by Z therapy - I have tuned them according to the video. The car is not running rich to the best of my knowledge. There is no air pump, with headers there is no exhaust gas tube, therefore no exhaust gases through the balance tube, the control valve is not hooked up. No water through the balance tube. The carbon canister purge valve has a crack in the lid, but otherwise seems to be intact. The car runs fine but after a strong acceleration the car wreaks of gas. Sometimes in the past to the point of eye stinging. …

Over in Fuel Injection it's mentioned that winter fuel is coming. Where I live we have some stations that sell non-ethanol blended gas that I use almost exclusively. This fuel will store much better than an ethanol blend because it doesn't attract moisture like ethanol and is way less corrosive on fuel system components. I guess this is just a reminder that winter is coming and there are a few months where I live that the 240 probably won't be driven. Do you guys drain the fuel system or fill it full and use a "fuel treatment" for winter storage.

So I have my swap completed and I have been running a little 40 dollar pump from autozone with a 35 GPH flow rate and 4 PSI and it seems as though my holley 4bbl needs a good bit more than that... With the carb tuned I can now get it to idle nicely and I even was able to take it up the road a little but if you put your foot down a little and get the thing past 3000 rpm it wants to shut off. It's just not getting the fuel.. Now I know that I should have the 80 GPH flow rate pump but it's just so expensive... I still have my fuel injection fuel pump and just ordered a pressure regulator. Will the regulator be okay under the fuel injection pump? I'd appreciate any help here.…

I put an Art Singer choke mount in and adjusted the cable ends at the carbs with the console out of the car. I installed the console a few months ago and the choke lever hit the console before "full choke". I took it back out thinking I needed to move the mount further up but it appears to be dead on per the instructions. Would it be okay to loosen the cable ends on the carbs and pull them out a little more? I'm thinking I can pull them out until right before they start to actuate the linkage on each carb then tighten the screw on the little barrels that hold the cables. Is it that simple or am over thinking this? That console is very fragile and expensive so I …

Hello All I'm new to this forum but not to Z-Cars. I first drove a 240Z in 1979 and in the years between there were 280ZX, 280ZX-TT, 300ZX and again a 240Z. My green 1972 240Z, was probably produced in September/1971 (VIN 048531) I would like to refresh the carbs and look for a repair Kit. Seems not so easy. I assume I do have the HITACHI Carbs (Round Top / 3 screws) Where can I buy such a repair Kit? Thanks from Switzerland - Daniel

Hello, I purchased a dual choke cable grommet/boot for my 1972 240z. I've done some console repairs specifically around the choke cable lever mechanism. Does anyone have any suggestions on how to install the grommet/boot? From the end of the cable attached to the carb? This would require removing the boot and crimps right?

Hello everyone, making great progress on the Z. Two weekends ago we got the car running. We used starter fluid to start her up and then light throttle to keep her on. The week after I buttoned up most of the fuel lines and a quick spray of the starter fluid we got the engine running again and maintained with throttle. We tried to start it again yesterday and it started up without starter fluid. Yesterday I tried again, no luck, tried starter fluid but stays on then dies even with throttle application. We are getting fuel at the carbs, I am assuming there is a blockage from the float bowl to the dampers. Also I know for sure the timing is off but I wanted to set the ti…
