I posted too soon, having insufficiently tested the secondaries. I know I was getting some action because the white spring (very weakest) gave that hoppity-hoppity bog when I put my foot into it. However, I put the original spring (a long yellow, NOT the plain that is specified in the literature) back in, put an index on the vacuum rod and went for another drive. No motion at all - not more than perhaps vibration movement of the index.

The problem here is that the plain spring is supposed to be stock; it's the third strongest. Instead, I find the long yellow in there - the third weakest. I've put the short yellow in, the one between the long yellow and the white, and will drive it tomorrow.

I also put on the 0.037 squirters and that again had a little effect on the bogging.

I need to get the carb into the secondaries before I screw with anything else. If the new vacuum spring works, I can start on the other tuning from baseline again.

Yes, this is a new carb. I have the Holley here if I need it but wanted a new carb, and a BG, before I started putting a ton of time and money into tuning.
