    When I was still getting my car running on the round tops, I propped up my center console and pulled the choke cable completely out of the sheath. Once out, I cleaned it thoroughly and applied some light grease I have for door strikers and hinges. I fed it in the sheath and back out again. I wiped the cable with a shop towel and repeated the the process until the amount of black particles left on the towel was negligible. Once clean, I applied a small amount of grease to the cable and put everything back together. It made a world of difference.

    I may try to restore my stock cable for a spare using just that technique. For now I just use this NOS cable. It will be fun to try to fix the old one though!

    That's the exact cap that I have on mine. I bought the cap in a pack with other caps of various sizes from a local auto part shop (Kragen Auto). I believe you can get them through any auto parts stores.

    I just won a nice set of 72 carbs on eBay as spares. Plan to send my current carbs to Z Therapy to get them reworked in the next few months. My forward carb is just developing a bit of throttle shaft play.

    UPDATE:

    Ztherapy was amazingly fast in getting my new fuel lines back to me. Great service. IF you recall, I had a leak on the bottom of the fuel bowls on both carbs. Or so I thought. I installed the first line no problem and sure enough the line was slit letting fuel just pour out. When I went to install the second line, I noticed the fuel nipple coming out of the bottom of the bowl was bent 30 degrees to one side. The fuel line was fine, but the boss was cracked right where the brass nipple goes into the bowl. I have NO idea what I am going to do now.

    This was obviously handled VERY poorly by the shipping company. Looks like it may have been dropped directly on that nipple. I imagine that these are pressed in. I am thinking I may have to pull the carb off and send it back to ZT. Bad setback.

    That sucks. You can probably just remove the fuel bowl and send that back to ZT rather than taking the carb off.

    Did you catch up with Steve via the phone? He is very responsive to customer issues as infrequently as they arise. 503-365-8583 will get him at the shop.

    Not yet, I did not want to bug him during the weekend. I will call later today. He was a pleasure to talk to with the fuel lines.

    UPDATE:

    I know I have more updates than bad microsoft software, but in case people are interested.
    I contacted Steve at ZT and he was more than happy to take care of my problem. I will be sending the carb back to him to have him install a new bowl and then it will make its way back.

    Merry Christmas to ZT and great customer service.

    Great service indeed

    Patience is definitely important for the older cars as I have learned over the years. You are going to love having fresh, and balanced, carbs.

    While I am waiting for my new choke cable to show up, and my rear carb to come back from ZT, I decided to take a shot at fixing my old choke cable. Holding the wire with vice grips set on gorilla tight, I tried to move the cable. No dice. I am going to try to spray some liquid wrench in there to wiggle things out.

    ON a happy note, I swapped out my old coil with a shiny new chrome Pertronix flamethrower!

    Default Wow

    UPDATE:

    I cannot express how wonderful my new carbs work. I received the carb with the bent float bowl outlet back yesterday in wonderful shape. I was able to bolt it back together and get it tuned in less than 45 minutes. It was that easy. I find the fuel mixture to be about spot on at 2.5 turns out.

    What can I say about how these things run. My idle is rock solid at 750 rpm, and will actually idle down to 500 rpm quite easily. The throttle response and smoothness of the throttle is amazing. I had the sticky 240Z throttle that so many of us have with my old carbs, that is gone with my ZT carbs. Its such a joy to be able to glide away from lights as if it were a fuel injected car.

    Performance. In a word, awesome. My stumble I use to have at around 5500 rpm was not my timing or my dizzy. It was in fact my old carbs. I was able to rev to 6700 in second with absolutely NO issues at all. Smooth as melted butter in a quart of Amsoil in a rolls royce driven by angels.

    Starting is so much easier with a functional choke cable and the way the car performs very well. No matter what your SU issues are, ZT is your solution. They have been a joy to do business with, and words like integrity and service which are so missed these days seem to be a hallmark of Bruce and Steve.

    I always thought my Z was tuned pretty well, now it is as close to a new car feeling as it has ever been. I am stoked!


    Here is my baby finally back after enjoying some spirited driving today...

    BEFORE:


    AFTER:

    I still need to get a hose from my valve cover to the air cleaner housing and run a vent tube from the front carb float bowl to the air cleaner housing.

    Summary.

    Installed polished manifold and ZT SU's
    Refurbed my old air cleaner
    Installed flamethrower pertronix coil
    Installed new thermostat
    Refurbed fuel line
    Refurbed Thermostat Housing
    Refurbed heat shield
    New braided OEM braided line from balance tube to crankcase

    Glad to see you're as happy as I am with the ZT carbs. It looks like you got the upgrade finished in just enough time to consider it a Christmas present, as well.

    Looks great! Tuned carbs and a working choke are nice things to have. It probably feels like a totally different animal. All the little improvements do add up in the end
