The New, Newer Project: Part Tres...

[njsteve]

Next project is to reinstall the original 7043270 800 CFM carb. The man I bought the car from purchased an NOS 800 CFM, 17054910 service replacement SD455 carb from HO Specialties twenty years ago and installed it because he thought there was a problem with the carb. It turned out the problem was with the TCS system cutting off the advance, so he routed the vacuum advance directly to the carb and cut out the TCS system. The car ran fine then, but he never reinstalled the original carb. So I will get a carb kit and replace the needle and seat, and the accelerator pump with something that will tolerate the new ethanol blended fuels we have to put up with. Then the original carb goes back on.

Here's what's on the car now. 17054910 dated "1140" 114th day of 1980






And the original 7043270 dated "0133" 13th day of 1973:

Thanks! One of the posters on the PY website asked about the master cylinder date code stamping. I didn't know there was one but here it is. It is stamped in tiny font on the front outlet. CS3190 is the CS master cylinder as documented on the paper tag on the retaining wire, 3190 is the 190th day of 1973.

The reproduction New York license plates arrived today. 956-LYS was the plate originally issued to the Enrico when the car was new. I still have the very first registration from the stack of registrations through the years. www.licenseplates.tv reproduces any plate for around $85. They do really nice work.

Nice indexing of the license plate screws, Steve!

OCD at its worst!

I was finagling with the original carb tonight and found this oddity in the fuel inlet. I have never seen a check valve in a filter cartridge before. The replacement Delco filter just has a paper gasket on the end. This rubber seal and check valve was pressed into the inlet of the original filter. It takes some serious pressure to unseat the valve. Was it an anti drainback valve?

I find these in Oldsmobiles all of the time and yes it is an anti drainback valve.

I wonder what the efect is on flow restriction into the carb?

[napa68]

It was my understanding Steve, this was to prevent fuel flow in the event of a rollover. It takes fuel pressure to overcome the spring.

I want to give a shout out to members &quot;KevinW&quot; in NJ, who found the Milwaukee craigslist ad for two NOS tires, and &quot;67442&quot; (Paul) in Wisconsin who then proceeded to play the middleman and run down to the seller's shop and pick up the tires for me and then wrapped and shipped them to me. I now have a full display set of 1973 date coded Firestone 500 Radials. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

The original spare (in the middle) and the two original tires (on the left) from the car are date coded the 18th week (late April) of 1973. The two NOS tires on the right were produced during the 25th week (mid June) of 1973, which makes them all perfect for the late July built car. And best of all they all have the unique, early 1973 white Firestone shield logo which was discontinued in late 1973.



I also got a tip from Paul on how to get rid of that white waxy stuff on the tire surface that no solvent would remove. Paul said it was the original mold release material that outgasses from the rubber over time. He recommended using a hair dryer to melt it and to let it soak back in. I used a heat gun set on low and whodathought but it worked great! I would heat the stuff and it would instantly melt into a glossy liquid which could be wiped away. Then another application of heat and the remainder would soak back into the tire!

Here is the original spare before:



And after using the heat. (disregard the white in the treads, that is tire dressing that hasn't soaked in yet)
