Thanks Gav. I'd rather not cut the trans tunnel, so I might try to weld some extra length onto my current gear stick to get it back close to the original length. Thanks for the info!

I have a 1971 240z. It definitely needed the bend in it to get through the hole in the trans tunnel. The speedo is also incorrect, so your theory sounds pretty plausible Gav. Is there an easy way to ID the gearbox? Is there a difference between the gearsticks on the later gearboxes (71B vs 71C) or would either of them do the job? Anyone have a spare they would be willing to part with? Thanks!!

Here's what is in there at the moment. It has heat marks around the bend in it so it may not be original.

I'm bringing this topic up from the dead because the problem is fixed now. I replaced the coil but that didn't fix the problem, so i bit the bullet and took it to get the carbs tuned by Steve at Paul Pavlou Motors on a rolling road dyno. The choke cables were sticking a bit and they also reset the float levels and tweaked the ignition timing slightly. Problem fixed!!!! 97.6kW at the wheels. Nothing to set the world on fire but better than I was expecting for a stock L24 if I'm honest. Have taken it for a good drive and managed to wind it all the way out a couple of times. No misfire and it pulled really well. Stoked. Would recommend Paul Pavlou motors to anyone looking to get carbs tuned in Adelaide. He did a great job and was a gentleman.

Looking for a gear stick for my 240Z. My 5 speed gear stick has been cut down and I'm going back to a more original look. Cheers, Jon

*Update* Still not fixed... Just replaced the damper oil with some pneumatic tool oil that I had sitting around. It looked to be around the same consistency as water, so pretty thin, but no change to the misfire. Was worth a shot and probably can't hurt though. I also double checked what I had put in there and it was 10W30 - not 10W40... I've given it a suck and can seen the arm move inside the distributor. I think i also checked it when i checked the timing by removing the vac hose and seeing the timing reduce. I'll have a better look on the weekend. The rotor doesn't seem to have much play though and the cap, rotor and condenser look almost brand new. Any more suggestions before I reluctantly change the float levels?

I though if the oil was too heavy, I would create a rich mixture at WOT instead of the lean mixture i'm seeing. If the dashpot is slow to rise, then the venturi sucking the fuel will be stronger according to this. http://www.classiczcars.com/topic/45956-pneumatic-tool-oil-in-sus/page-2. In any case, I think trying some lighter oil is a good idea. A lot of people do say they run sewing machine oil, so I'll give it a go next weekend. I'll let you know how that goes. I have 12V points ignition. I did wonder if the miss was due to higher RPM scatter or incorrect dwell. The points look to be quite new and looking at the plugs I can see that they're definitely lean so I thought I'd deal with that first.

Yes, I believe so. I disassembled and cleaned the carbies when I put the kit in them. I used 20W40 for damping oil as I couldn't find any straight 30Wt. I put slightly too much in and some overflowed into the carby while driving, but I've cleaned this up. I've also noticed that if I rev to high RPM at half or 2/3 throttle, then the miss is worse. I guess the damping oil would have a bigger effect when RPM is changing faster (ie less effect at part throttle). So it is slightly worse when the damping oil is having less effect.

Thanks guys. Yep, bought it from Adelaide. The body's been done, it's quite original and basically everything works (even the clock). Just what I was looking for! Sorry George!! I did need some work. It had British SU's on it, which were running very rich. I've replaced them with 3 screw Hitachi's but I'm having some issues - see my post in the engine section. The shocks were absolutely stuffed, so i've replaced with with some adjustable Tokico's. Getting them was an absolute saga, they arrived 9 months after I paid for them. The seats are pretty knackered too, but they'll be fixed up soon enough. A few other little projects to do, but they were the main ones for now.

I'm having problems tuning my SUs. Any suggestions for what to do next? It seems that they are OK or slightly rich at low RPM and low engine loads, but when I go for a spirited drive and check the plugs they look white and very lean. The engine also misses at high RPM - not a backfire out the exhaust or carbies, it just misfires and stutters. Here's a more detailed overview: Engine - completely standard L24, except for headers and a 2.25" exhaust. It is a little bit tired, but still has compression of 162,171,161,178,171,175 Ignition - timing and advance checked OK as per FSM. Carbies - 3 screw SU's with standard N27 needles and 20W40 oil in the dampers. How I tuned: 1. I set the float heights to 23mm below the top of the float bowl cover. I did this with a mark on the outside of the bowl and a clear tube from the outlet. 2. I adjusted the mixture nuts so that when the piston is lifted slightly, the RPM rises slightly then returns. 3. I set the idle adjustment screws so that there was even airflow at idle between the carbies. Other things I've checked. * Put a new kit through the carbies including new gaskets and new jets * Checked for vacuum leaks and couldn't find anything major. The throttle bushes have a very small leak, but I think that's quite common. * New high tension ignition leads fitted Next step? I was thinking of raising the float level to richen up the high RPM high load then adjusting the mixture nuts for lower engine load. Is this reasonable logic, am I missing anything???

Hi everyone, I've been looking around the forum for a while now and thought it was about time I introduced myself. I'm Jon, I have a '71 240Z in OK condition but with enough still to work on to keep me happy. I've had it for about a year and a half now and I'm still very happy with it! I'm not completely new to Datsuns, I had a 260Z 2+2 when i was at uni and my brother has a 1600 that he's restored. I have a few projects that I'm stuck with so I'll be making separate posts about them. That's me. Nice to be here! Here's a pic of my 240 with my brother's 1600. http://www.viczcar.com/gallery/displayimage.php?pid=3624&fullsize=1

Hi, are these just a pair of shocks or do you have a set of 4? If you have 4 I'll take them.
