To get back to the questions that I have been asked -
I pulled the Braswell (Holley 4150 style, 700 CFM) carb off, and took a good look at it.
On the Primary Metering block it is marked:
PRI 5882
4776 (I think this is a metering block #)
39 59
SEC 6502
4776 (I think this is a metering block #)
40 67
Under the carb, I found a little vacuum port that was capped off. It looks like it goes to manifold vacuum, but I have to find out for sure. The cap was very degraded, and I replaced it. If it's ported vacuum, I could use it for my vacuum advance.
The primary has two screw in Idle Air Bleeds, both marked "73".
I used a little tiny wire on the smallest holes, and a larger wire on the bigger ones. They all seem clear, I squirted carb cleaner down there too.
The shooters are: PRI 31, SEC 28
The cams look like they are white, or a clearish, yellowed plastic. I think they are the same color. Both are configured with the screw in the "#2" hole.
Both Accel pumps fire as soon as the throttle is opened, or the secondaries (mechanical) are opened.
There seems to be a little leak near the primary accelerator pump.
I am planning to take the carb over to Braswell to have them take a quick look at it tomorrow. I assume they can check / change out Power Valves if needed.
Thanks for the advice, and any suggestions also appreciated.
