Thermoquad help questions

OK, up and running. All settings were done according the manuals as I rebuilt it.

Improved throttle response over the 750 Edelbrock, even though I'm not getting a vacuum signal from the port on front. 6518S carb (440 Industrial) with only one port for distributor on front and the port for the pull-off in back.

If I blip the throttle lever I get vacuum for a split second, then back to zero. So driving I probably get some advance for just a bit.

I can adjust idle mix to 14-15 on the A/F meter, but with any throttle at all, it goes to the meter limit of 10 A/F. Running along at low speed cruise (idle circuit) it's OK, but then with throttle in the 10's at best. I backed off the small screw on the rods and it seemed to help just a bit. But I'm way rich.

Does seem to have some unevenness mid throttle. So where do I start??
