    240z floor pan replacement question

    I'll be using a gas shielded mig. If I butt weld and my welds have pinholes will seam sealer make everything Waterproof?
  2. I'm going to replace the floors in my 240 over the winter and I've read as many old posts on the topic as I can find. After all that reading I can't figure out if it is better for me to attempt a butt weld or overlap a bit and weld a lap joint on the inside of the car. I'm a novice welder and while I plan to practice a ton before I start I don't want to take on a butt joint if I have little chance of success. I'm also wondering if I do a lap joint do I just weld on the inside of the car? Do I then fill the seam under the car with a seam sealer? How far should I overlap the new pan with the old metal? I'm looking to get the ZF pans and rails. Any thoughts/comments are appreciated, Thanks!

    72 240z choke handle

    I guess I have a bigger issue than just the knob. My entire choke lever and cable assy was missing so I got one on ebay and upon inspection it isnt correct. Im guessing its from a 260z. If anyone knows where to get the lever please let me know!

    72 240z choke handle

    That looks exactly like the 70-71 knob I got from ebay that doesn't fit. Perhaps they just look the same have different mounting styles. If you have one it better shape great but if not that one would work fine. Thanks!

    72 240z choke handle

    7tooZ- I sent you a PM about the knob. Thanks
  6. Does anyone know where I can get a choke handle for a 72 240? I can't find one anywhere. Thanks!
  7. I though about that a bit. Im going to head down that path this weekend
  8. When you immediately press the gas pedal just a tiny bit (when it dies) the accelerator pump isn't really doing anything yet. All the pump cams have a very similar initial rate so I'm not sure if that will help but its on my list anyway. I read something about immediately off idle is the point when the carb transfers from the idle circuit to the transition circuit and that can be lean if the butterflies are too open at idle. I just wish I has a stock set up!
  9. Quick update. The Holley carb was way out of tune and the secondaries weren't even opening. Its much better now but still has a slight stumble when you first touch the gas but I'm not sure if its lean or rich. And this was supposed to be easier to tune then the SUs????
  10. I was thinking something similar so I plan to replace the cap/rotor, plugs and wires with good stuff. In addition I found the air mixture screws on the carb were not set equally- one at a 0.5 turns and the other at 2.5 turns so it makes me think I need to make sure the carb is set up ok. Thanks to everyone for all the help!
  11. The receipt says its the 8007 Holley that is recommended by Arizona Z Car. The accelerator pump looks to be spraying fuel fine. I did pull the plugs to take a look and found some odd stuff. The cylinder 1 plug looks fine, 2 and 3 are extremely carbon covered and 4, 5 and 6 have moderate carbon. Not sure what this is telling me quite yet.
  12. Stock L24 engine. Per the service records / previous owner it had plugs/cap/wires and a valve adjust in the last 5K miles and it has an electronic ignition installed. I still need to verify the timing and also compression.
  13. I just picked up my first 240Z in 20 years and this one has a Arizona Z Car intake with the Holley 390 CFM 4 barrel carb. The car has a noticeable stumble off idle and a lack of low end. It seems to do OK at higher RPMs but it seems sluggish compared to what I remember my old Z to be. I've read a lot on this site about the AZ/Holley combo and it seems that some love it and some hate it. Are there any tuning tips for this set up? I have no experience with the holley carb so I don't know where to start. Previous owner said it has been performing that way since install. I would like to put SUs back on but its financially not in the cards now. Thanks for any help!
