There's one thing that I've been meaning to ask about. Have you checked that all the carb linkages are working as they should to bring in the carbs when they should?

They all open up to full throttle and they work in progression. How "right" they are remains to be seen.
This is the first tri-power that I've owned, and I have to look into it some more. This thing I have called
"a job" takes up a lot of my time!!

Factory timing = 7.5* --- factory idle is 650 rpm. We have it set at 10* and 750 - 800 rpm. We currently don't
have vacuum advance working, so we aren't finished 100% with the idle tuning process. I believe that next
Wednesday the center carb will come off and the vacuum issue will be fixed, then we will do the final
tune on it. The goal, before the tach was installed, was to make it so the car wasn't cackling at WOT,
which we accomplished. Putting the correct plugs in it and checking over the wires and points gap is
part of getting it to a baseline. It rained yesterday, so I couldn't take it out for a test run. It'd be nice
to see it go to 5000 rpm smoothly and to idle at a steady number when the work is done.

I should also have asked what do you know about the cam as far as recommended idle RPM, power BAND, etc.

The previous owner gave us the cam specs, but they are in my barn now. I'll post them this weekend.
I know that it's a .540 lift cam, but don't know duration and such off the top of my head.
