What I Did Today
25 years ago (well, closer to 50 years for some of us) boats, blondes and beer WAS comfort. Staying home was agony. I can't imagine being cooped up these days if I was still a young man. All that adrenaline and testosterone going to waste. Not good.

COVID-19
Florida reports over 15,000 new Covid-19 cases in a 24 hour period. If Florida was a country, they would rank in fourth place in the world for the most new cases in a single day behind the United States, Brazil and India. HUFFPOST.

1970 Franklin Mint 240Z up for Auction on BaT
Has anyone asked BAT about the favoritism? My suspicious mind suspects something like a kick-back of funds to someone at BAT.

I vote for original paint and fix the dings. It's identical to my first Z. Sigh.

Need help with balance tube and cooling bypass
That kinked float bowl to fuel nozzle hose is going to be a problem. That hose needs to be super flexible (Ztherapy hoses are silicone). Normally the problem isn't in the fuel delivery to the nozzle. Stiff hoses will bind up the nozzles, preventing them from returning to the non-choke position (up) when the choke knob is forward (off). Looking at the pic again, You might be able to relieve some of the kink by reversing the hose.

If I remember correctly @siteunseen has plugged those coolant lines.

Welder advice?
Co2/argon is my choice for shielding gas but pure co2 will work as well as the mix. I used it for years in one of my jobs. I've found there's a bit more splatter to clean up but the big plusses are the cost and you get more co2 in a bottle than co2/argon mix. It was explained to me by an employee of Airgas that when you add argon to co2, the gas will no longer compress into a liquid. Using argon/co2 you'll have less clean-up but higher costs.

Round top carbs mixture screw all the way up but still orange color tune
I'm going to assume the floats are set correctly and the mixture screws are about 2 1/2 turns down, correct me if I'm wrong. Try lifting both carb pistons and drop them at the same time. They should be very difficult to lift but should drop at a much faster rate. Both should feel the same when you lift them and they should land at the same time or nearly so. Compare the piston heights when it's idling, accelerating and at about 3000 rpms.

The valve seals are known to go bad long before piston rings.

New Z Owner
Pull the sending unit and assess the amount of crust on it that may be preventing movement. Don't try to move it if it's stuck. Check it for electrical continuity with an ohm meter. If the circuit is good, soak the unit in CLR for a day or two until it comes out clean.

Nissan Z: 50 Years of Exhilarating Performance
You're correct that there were no Nissan dealers back then in the early 70s, however, there was a Nissan (factory) building in Beaverton, Oregon. I knew a fellow who worked there.

There are those exceptions that were driven on the highways most of the time. They generally don't show as much interior wear.

Remove the Kubota names and put Tonka on it. After all, It's just a big sandbox toy for big kids.

DHLA 40 question. Running pig rich!
3.5 psi is a good pressure for carbs. Have you done a fuel volume test. Pressure and volume are not the same thing. You can have one without the other.

COVID-19
Things (prevention) are more clear to a lot of people but not everyone. It really is too bad that mask wearing is becoming a political statement. This latest surge is caused by lack of social distancing, period. When people get together without due care and caution, there'll be a surge in Covid-19 in that area within a week. !5%-30% (depending where in the world they are) of hospitalized patients require renal therapy (or outpatient dialysis) due to kidney failure. Currently, there is not enough equipment or technicians to deal with a substantial surge in Covid-19.

Gauges stop working then begin working again
Resistance causes heat at the point of resistance. If the blades that hold the fuse are clean, take a look underneath it. Frequently the soldered wire connection to the blades needs resoldered.

Where to locate a fuel pump inertia kill switch
The installation instructions caution about moisture (water, coffee, etc.) and state that the passenger compartment is recommended because if it does trigger you won't have to get out of the car to reset it.

What is the theory behind the brake adjustment?
Are saying the star wheel and the hole don't line up, making them non-adjustable manually?

240z wiper arm ID
A quick look on Trico's website didn't turn up any of your numbers. They do have 15 different wipers listed for early Zs. Left and right wipers are the same.
