Mystery Switch
Thanks guys, that makes sense. I was running the dizzy with only one of the points, so the thermo-switch connection to the missing points must be tied up somewhere. Going to track it down just for laughs.

Mystery Switch
I put the switch in the freezer for a bit, and now I have continuity through the switch. Pretty sure it will open again when it warms up. I'll see if I can track the wiring tomorrow if it can be done without too much collateral damage.

Mystery Switch
Haven't done anything on it today, will try it in the freezer tomorrow. My car is an autotragic, by the way.

Mystery Switch
The switch is reading open. There's no A/C on the car. I can manually trace the wires but wanted to avoid creating a mess. Looks like a factory install, but can't be sure.

Mystery Switch
Does anyone know what this is? It looks like a thermal switch (due to the potting) but I'm just guessing and couldn't find it on a schematic. Switch was located just below the emergency flasher relay on the RH side of the passenger kick-panel of my '71. Ran across it while troubleshooting my rear window defroster. Thanks!

Mechanical Fuel Pump - Slow return to start position
Perhaps you need a new return spring? Make sure there is not a build up of gunk around the lever/ return spring area. When I was checking my pump (removed from the car) it would return quickly with an audible click. I also have an original '71 Nikki pump. My luck with after market pumps has been pretty bad, the majority of them are junk.

Brake Master cylinder woes
I took the forum's advice and tied a gym sock around the end of the master cylinder otherwise I would probably have a new implant!

Brake Master cylinder woes
The heating and oil didn't work, so I kludged a brass air fitting to the fwd reservoir with epoxy and clamped the other fluid outlets shut with C-clamps. Once the air pressure reached 80 PSI, the stuck valve popped out like a gopher!

Brake Master cylinder woes
I currently have a later version on my car. The brakes work fine, albeit they seem a little touchy. The biggest problem is you that have to swap the front and rear brake lines that go to the master cylinder. This requires physically bending the brake lines.

Brake Master cylinder woes
Thanks, Patcon, will give it a try. Heated it in a pot of boiling water mixed with WD40, no luck. Tried the freezer, too, without luck.

Brake Master cylinder woes
Good luck finding the correct master cylinder. I have been trying to restore my original master cylinder (7/71) but have been unable to remove the fwd piston which is stuck inside. This is an off and on again project. Been trying for a year to find an original master cylinder with the front brake reservoir in front with no luck. Make sure you check that the fwd reservoir is stamped with an "F" beneath it, one fellow just switched the reservoirs on top and trying to ply that off on me as an original.

Condenser failure
Glad you got her going, electrical issues can often be quite mysterious.
-
Condenser failure
Have you tried a new condenser? Just removing it from the circuit won't do it, you may get a weak spark without it, but it won't be enough for ignition. The condenser isn't there just to protect the points but to also provide a strong spark.
-
Condenser failure
Try another new condenser, purchased from a different source than your last one. Last year I had some vexing ignition problems on my '71, and finally concluded that it was my condenser. The car actually ran for a while after the second condenser replacement, but then quit with no spark. Finally switched out to a Pertronix coil and inductive pickup, and it's been running fine since the switch. Still using the original dizzy. If you stick with the original setup, have found that the Delco condensers seem to be the most reliable.

Interesting Video Restoration
Great video, Mike. It's great to see real craftsmen at work.

Starts when cold, then won't fire again
Anyone think this could be an issue associated with the ballast resistor?

Gunson Colortune Always Yellow
Thanks, Yarb. I saw the Feb date but not the year. lol

Signals acting up
Amazing that old flasher is still ticking!
-
Gunson Colortune Always Yellow
I know you have the choke cables disconnected, but just make sure they aren't sticking closed. Had this happen on my '71, and it drove me crazy.

1970 240Z Works Rally - the road to restoration
Great video, thanks! And the Z's took both 1st and 2nd.

Seeking Heater Box Refresh / Coolant Work Advice
Refurbished the heater box in my '71 last winter. Discovered a few pinhole sized leaks in the heater core and decided to use some Bar's radiator stop leak in lieu of replacing the core. So far, so good, no leaks with the heater going (never cold enough here to use it, but I do test it when I take the car out). My car is an auto transmission and does use the transmission oil cooling. Sorry for the late addition.

Wiper rebuild
After taking a second look at the closeup picture, I realized that the positioning of the passenger side linkage going to the pivot was wrong. I installed the linkage on the outboard side of the pivot, not the inboard side per the picture. Common sense should have told me that it was oriented wrong, but a picture is worth a thousand words. Once corrected, the wipers work like new. Thanks again for the pics, Richie, I'll be sure and take more before I tear anything else apart.
