"Edison" batteries were available, and had some advantages over lead-acid, but they could not deliver high current on demand.

We have better batteries, and better motor controllers, but the batteries remain the weak link. IC powerplants have also improved dramatically in the last 120 years, and now start and perform as quietly and smoothly as electrics, thus obviating the primary advantage of the early electrics over IC.

With two-piece driveshafts, u-joint phasing is important. If the driveshaft was removed recently and not replaced exactly as it was, it could cause vibration. That's true of a two piece or one piece drive shaft. Driveshaft vibration often occurs within a certain speed range, and it may be accompanied by a humming or low growling sound.

It's normal for the engine to shift on its mounts when under load which can cause normal mechanical sounds and vibration to be transferred into the frame and body under some operating conditions. I'd look real carefully at the exhaust system and engine/transmission mounts. Next would be the drive shaft, and then wheel bearings, underhood accessories, and rear spring shackles. Defective or modified exhaust systems can produce odd sounds.

In some cases, a clogged transmission screen can cause odd sounds, and low power steering fluid can make assorted noises in the system.

It could be many things. I'd look for any evidence of an exhaust leak, and any evidence of any part of the exhaust system contacting the frame when the engine is under load, or any exhaust system hanger problems or modifications. Loose baffles in a muffler can cause strange effects. U-joint issues can cause noise or vibration or both. Wear, improper assembly, or lack of lubrication are some things to look at relating to U-joints, slip yokes, etc. Another area to check carefully is engine mounts and transmission mounts. I'd look at body mounts too, and check all engine accessory mountings and belts. Anything loose anywhere in the car, including the spare tire, jack, etc can make odd sounds under some operating conditions. In one unusual case, a small dent in the air cleaner housing caused a moaning sound at a certain speed. I'd check the rear axle lube, attachment hardware, shackle bushings and shock mounts.
Tires can make odd noises, so checking tire pressure and wear patterns is a good idea. Some pavement surfaces cause noise, so drive on a variety of surfaces and see if the sound changes.

I think that opening is NPT pipe thread. Putting a fitting or short pipe nipple and hose in it will prevent flooding the starter with dirty water.

A new swamp-type cooler may be available. These were once popular in the Southwestern states. They attach to a window opening and blow fresh, cooled air into the car. They are ungainly looking, but period-correct, and they involve little or no modification to the car. They work well at altitude and in areas with a dry climate.

That's an odd situation. Are you sure that you don't have a leak at one of the carburetor body gaskets or perhaps a manifold gasket?
I believe that carburetor should have a thick heat insulator/spacer between it and the manifold. It doesn't appear to have one. Lack of the spacer can allow the carburetor to get too hot, which can affect the fuel mixture, especially at idle and low speeds.
If the idle mixture screw is actually turning, putting a small washer or two or three under the spring should stop it. It may be the wrong spring for the application.
