You might want to look at this video about brake adjustment if you haven't worked with drum brakes before.youtu.be/T1Zc3aW18Z4

Is your air cleaner complete and in place? The air cleaner is both an air filter and a silencer. It's normal for the carburetor to make hissing or moaning sounds. The air cleaner assembly eliminates the intake noise, filters bugs and grit out of the incoming air, and acts as a flame arrestor in case of backfire.

I had taken off the top portion to check where the sound was coming from…definitely a vacuum type sound coming from throat of carb…I can clearly hear it when engine is running so it’s pretty loud… I don’t remember that sound many years ago when I use to drive it

Jimmyk;
Two symptoms here: First the possibility of a rich condition as evidence by the spark plugs, second the whistling somewhere in the carburetor throat. I would investigate the choke system first. To conduct the proposed test the entire air filter/silencer will need to be removed. With the engine fully warm and running try rotating the choke plate in the direction of ‘choking’ the engine. Easy does it, just a little bit of force against the bimetal with your finger . . . not enough to alter the mixture. After that try pushing the choke plate to the full open the position . . . hard against the stop. Did the whistle sound change during this test? If it did then let’s start looking at the choke adjustment, especially if the noise stops when the choke is full open. It other words, if the whistling stops when you push the choke full open I’ll go out on a limb and say the choke is not adjusted correctly. Later we might want to investigate the choke vacuum piston condition, but that’s a subject for another day. I’ll be first to admit my experience with your Stromberg carburetor is extremely limited, but some of the design concepts appear to be the same as the later Carter designs. If the choke vacuum piston detail is an area of similarity, I believe once the choke plate achieves the full open position the air flow in that system is blocked by the motion of the piston, therefore the air flow in the choke system should be zero, or near zero with the plate full open. The Stromberg Manual available on this site (see StrombergManual.pdf (packardinfo.com) does not specifically state the cut-off function, but the artwork on page 2 (page 15 of the PDF) suggests air flow cut-off is likely with the choke full open. The integrity of the choke vacuum passage ‘Welch Plug’ should also be inspected. If in doubt a bit of paint along the outer diameter of the plug should seal it well enough for you to determine if that’s an area that will need attention. In the same vacuum passage there appears to be a lead plug, again a bit of paint will seal that area for enough time to conduct the test. The choke circuit might whistle during warm-up but somewhat silent after that. The above testing is only trying to determine if whistling airflow is associated with the position of the choke plate and therefore the piston position. The Welch plug and lead plug if leaking will whistle independent of the choke plate position. dp Edit: I can't seem to get the links to work correctly when using Word as a means to compose the message. Perhaps someone with more savvy will help. packardinfo.com/xoops/html/downloads/StrombergManual.pdf It works OK when I paste directly into the posting, but not when using Word.

Ok…thank you..I just got back home and will take a look tomorrow and do what you described…my carb is the wa 530s carter…some models had the Carter but I believe mine came from another Packard long ago…hopefully that’s good news as for your experience with carters…I’ll report back tomorrow,, thank you

Word processors such as Word typically do not use a standard character set and often change characters to alternate versions that can cause problems when using for things like this. If you're going to write somewhere else then paste in, use a pure text editor such as Notepad.
