1967 273 4bbl with Edelbrock 500 CFM Carb
I also noticed that the fuel filter is only half full it’s never been like that since I’ve owned it so not sure what’s going on. The bowl got down to half way when I had gone for a drive for like 20 min. As soon as I let it cool and turned the car back on again it was full so not sure what was going on. Fuel pump? I’m pretty new to engines this is my first project car so trying to focus on making her drivable and safe for distance. I attached photos and a video for reference.
A portion of the fuel will vaporize summer engine temperatures. Fairly normal. its why the outlet of the filter needs to be higher than the inlet. This helps the vapors escape through the carb without pushing a bunch of fuel into the carb bowl. Chrysler explained this in a 1963 master tech booklet.
Speaking of which
Here's a fairly complete list.

when a link fails, I find its usually because they loaded the page as Jpeg and then linked as jpeg or visa versa.
Sometimes its easier to note the MTSC year and session number, then go to mymopar.com and get the filmstrip or booklet there.
hard shifting is also covered in those booklets and filmstrips. You'll want the ones pre '67 if you are using the original 904 and linkage.
As far as mixture adjustment at idle. First. the timing should be around 10 - 12 at something like 600 or 650 rpm. If the rpm is higher, then the distributor may be advancing. So lets say you set it at 10*BTDC at 800 rpm. When you slow the engine to 650 rpm you may find timing is then 8* BTDC. Follow? You need to adjust everything a couple times or more to tune it in. (all done with vac advance hose plugged with a golf tee or such)
The idle screws are adjusted by turning in 1/8 turn at a time until the rpm drops, then turn back 1/8 turn or so. It's easier to identify the engine performance falling off on the lean side than the rich side. So get the best running on the lean side in neutral/park , then make them a tad richer because when the engine is loaded (placed in drive) it will be stronger with a little richer than you found in neutral.
