Problem Solved, I feel like an idiot. One of the tiny screws holding the face to the tach had come off and caused the face to skew enough to cause the pointer to bind. Can you see it? Tach works flawlessly once again! Moral of the story: LOOK FOR OBVIOUS $^!#!!

SteveJ, where exactly is the resistor in the footwell area? And the TIU? See pic. The car is running great, no problems there. Got the pic of the plug outa the socket, I am continuing to wrestle with it.

Thought I had seen all the threads, but not this one. If I can just get the doggone thing out...... No changes to the ignition system. Ignition is an MSD-6A with adapter and all wiring to distributor and coil are intact.

The tach issues are: Has worked flawlessly for the past 2 years I have owned the car. One day, the needle was lethargic and didn't react to quick accelerator blips. Needle did move, but very slow. Also, never hit an appropriate high RPM (approx 3K or higher.) When engine shutdown, needle would slowly settle to somewhere between 500 to 1500 RPM. Able to tap on the tach to get it to settle to zero. Multiple tries after tapping to zero with similar results. Plenty of info on 240 and 280 tachs with lazy pointers, not much on the mighty 260!!

Thanks for the replies. I tried the "squeeze the sides" thing, I probably didn't squeeze hard enuf. Difficult to squeeze with 2 fingers and also pull out with the same hand. Ok, so I went back out to try again. Squeezed for all I was worth.....NoJoy. To be clear, I tried the "far", the "middle" and the "close" sides squeeze together with pulling the connector. Was able to work a second hand in there for the "pull." Nuthin.

Having Tachometer Issues and need to troubleshoot. Finally got the Tach loose and out the hole. I've tried everything....having a helluva time getting that connector loose, only enough room for 1 1/2 hands. What's the trick?

Thanks for the pump-up, DZCG....all good points! Just wish there was a "Local Mikuni Guru" who I could consult face-to-face who can point me in the right direction and feed me with knowledge of all the tricks. I will call Dave when I gather up enough good questions to ask.

Thanks, guys! Was actually hoping to have someone do the work locally since my skills are limited to "basic" at best!! Yes, I have read the thread....good stuff.

Shoot away, Yippi!

Need one to get my 40 PHH's tuned. Anybody know somebody?

Excellent, Mike. Grassy-arse!

Thanks, Madkaw and DM.......a lot of threads to sift through!! I do have Mikiuni's PHH Carb Service Manual, but looking for a manual or guide (if one exists) that can start me from the beginning at step one. I know the process is a lot of trial-and-error, but where to begin? This is all new to me, but I have the time and patience to learn.

Just acquired a 260z with triple Mikuni 40PHH's and would like to learn proper tuning techniques for these carbs. I've done numerous searches for any kind of manuals dealing with the subject, and the only one I've found is the "Mikuni PHH Carburetor Service Manual." Anyone have any leads on any other manuals that deal specifically with tuning these carbs?

Just bought a 260Z with a Mikuni 40PPH triple carb setup with TechnoToyTuning 75mm velocity stacks. PO running with no air filters. Can anyone with a similar setup recommend options for air filters? Plan mostly street use. Thanks!
