Here is the sad situation I have been living with my entire life. Back when I was a kid the USA and the UN had the "Population Control Council" or something like that. One politician on it was George Bush. At that time the USA was sending free birth control to 3rd and 4th world nations to prevent destruction of the biosphere. Then Reagan came in and destroyed that on the premise that no population growth would mean no asset appreciation for the rich and higher sales of BigMacs, Wrigley's chewing gum, cigarettes, and soda pop.

My generation was horrified and has the lowest birth rate of the 20th century. My generation has left fewer descendants around to suffer the coming calamity.

I don't know what this has to do with Packards except that the day is coming when they will be off the road.

I live near one of those stations. I will use it on my next stop and see if the data changes.

I don't think that tag was ever mounted on a car. It is probably a production sample that was left in a car and thrown in a drawer. We get that all the time in test cars.

What it is representative of seems likely 1929, in which as shown below, Dietrich badges were being mounted on the soon to be introduced lower belt moulding.

Below is a cropped example from 1929.

I have a problem with the authenticity of one of those items. That junknet premium of 18% is a joke. Where is the risk? 18% risk free money in a world where the cost of capital is rigged at -6%.

If I loan money for value added I lose 6%, but if I put somebody else's brick-a-brack in a junknet auction I get 18% with nothing at risk? Is this what those crackpot economists call "post industrialism service based economy"? Pass me a barf bag.

I bought one of those oval things for two bucks at Hershey at long while back.

I would put the subject between two pieces of heavy plate glass.

I made a light filter up using that method and it works great. I put it in front of the focal plane.

Those vacuum tanks can develop leaks that cause fuel starvation. They should hold vacuum when in the filling position, and the vacuum side should close off when draining. If you put a test gauge into the fill port you see the action on the road. If the vacuum tank never gets near motor vacuum the thing is leaking.

As well, I read an article about winters in the Northeast where the Hudson river regularly iced over and halted commuters for days. The railroads as well were commonly snowed in. That is why they built the H & M tube trains under the river. By the 1940's the problem was already subsiding. So when these cars were built things were different to begin with although the Harvey cars seemed to do okay in the desert.

The oil priming on choke is on the left side. Those holes on the camshaft side (right) are little mister holes that align with the slot in the skirt. I don't know why anybody would block them off except if they want stuck valves.

There are a lot of things people are doing to those cars that make me want to throw up. Even the "experts".

I use to get of a lot of scam-mail, but not anymore. Told them I was sending their note to the FBI.

When I was overseas we got death threats for telling them we were forwarding their notes to the security services. That was a great laugh.

I always felt the smart thing for the USA to do during World War One was to let Germany fund their planned Mexican invasion of the Southwest. That would be much less expensive than going across the Atlantic.

One area to avoid is sharp bends in the fuel lines. Those fancy 90 degree bends may look great, but they create a Bernoulli effect where a low pressure differential is created the same way as an airplane wing. If you look at the Model A the fuel line looks sort of ghetto, but that is the way Ford reduced those sharp bends.

The vacuum tank next to the exhaust manifold is required for the gravity feed. In 1931 they put the pump up front thinking that would be the coolest place and by 1933 moved it to the opposite side on the Eight cylinder cars, but kept a couple of very sharp bends with fancy fittings going through the frame.

These problems continue today. Tanks now are sealed to maintain pressure with relief valves to prevent excess, and pumps are submerged in the fuel, thus preventing any low pressure spots. But misfire conditions sometimes still exist that are remedied by changing the shape of the fuel lines in some cases. Even in systems running 450 psi.

Today we have great ways to use thermo-couples to look at temperatures along the fuel lines. I think Packard was groping for a solution. With a diaphragm fuel pump the intake valve creates low pressure to draw fuel and if bubbles are being created and merging everything can come to a halt. Testing with clear fuel line is one way to analyze the problem.

Ethanol slows the burn rate which makes the engine run hotter. That can be patched by changing carburetion which will increase fuel consumption even further.

According to a Packard service bulletin vapor lock in updraft carbureted engines takes place inside the carburetor.

The diesel fuel thing is something Model A owners have been doing for a long time. It actually provides a level of top cylinder lubrication, but also likely reduces performance. If there are air leaks in the system it helps to reduce that too.

And yes, I have gotten gaskets that are not made to pattern from reputable suppliers. It is a disappointing experience the same way as drop shipping scams on the junknet. Inspect all parts prior to assembly.
