Ok, one more question on the Holley jetting.
That's could be correct depending on the spring and the actual airflow.
Ever seen the logs I made on a chassis dyno with different secondary springs?
Have not seen your logs, but I'd like to.
I found one issue and fix it though.
This secondary vac can has the black two piece cap so the spring can be changed.
The little top piece that comes off to remove the spring sits on an oring to seal the can so vacuum can pull the diaphragm.
That top piece was not sitting all the way down on it's oring (There was a slight air gap)
I took it off the carb and tested it with vacuum and the actuator rod didn't move.
A couple of passes with a flat file on the mating surfaces to get the powder coating off allowed it to sit down on the oring and it opens now and holds vacuum.
Also put a new seal where it meets the carb body
The Wife is taking a nap now and the car is about 8 feet from the bedroom window, so no testing until later.
FYI, I do have a 214/224 cam in the motor, but I didn't think that was big enough to matter on the vacuum.
I can lock out the secondaries (just read your last post while I was typing)
It has a silver spring in it currently.
One thing I can't get my head around is when I put the paper clip on the secondary rod to test the opening of them the primary side looked good on the AFR.
That off idle rich spot was gone. WTH?:D
Thank you for your input on this.
I appreciate it.
