I seem to recall an old post about the aftermarket mechanical pumps not making good contact with the eccentric.

Pretty sure I have a float level tube and the carb sync tool if you want to borrow them. Just let me know and I will hunt them down.

My Ztherapy carbs came with SM needles instead of the stock N27. I think the SM needles run a bit richer.

Chat gpt is pretty good. I am getting hooked on it. https://chatgpt.com/s/t_6a0a437b9b608191ad3f471c8cb51968 Oil Type Approx.

Cross threading is the new self locking 🤣

I like @Captain Obvious idea of disconnecting the linkage and making sure the carbs are isolated. Hard to imagine restored carbs will not idle low. Is the vacuum thing on the manifold hanging up the linkage? Just a thought.

Did you spray around the throttle shaft bushings?

@SteveJ , thanks again. I installed these tonight. Very impressed with the lights. I was a bit nervous how the flat face would look on the z, as I my brain always thinks convex lens for the car. I like the look. Amp gauge doesnt bug when I turn them on and fuses are nice and cool. Huge improvement from stock!

Thats good to know. I know the changing all my exterior and dash lights to LED made a big difference. Instead of the fancy meter, I used the "burn my finger on the fuse" test. No burn with the LED 🤣

Thanks @SteveJ . Having the Koito label makes it even better.

Throwing it out there......You said you replaced the fuel pump. I have heard that some of the aftermarket pump arms are too short and dont make good contact with the eccentric (hope its ok to use that word).

Curious if anyone has used Zcar depot H4 headlights with LED bulbs? Wondering how they work and if you think they have a significant decrease in amps from the standard sealed bulbs. Z Car Depot IncHeadlight Upgrade H4 Bulbs LED Option 7Headlight Upgrade H4 Bulbs 7" 240Z 260Z 280Z - 800-866 (). New pair of 7" headlights with glass housings and H4 bulbs.

Congrats on the first drive! Hope you guys had a wonderful Christmas. I went with this kit for my car. After having numerous electrical issues on past z's, I thought this would be a no brainer to go with the LED bulbs and refreshed electrical harness. https://www.thezstore.com/product/85/60-amp-alternator-upgrade-kit-70-72-240z
