t_g_farrell is on a distinguished road
I put the nikki on tonight. It runs but has a high idle 1500 or so. Other than
that it seems to work pretty well. I will have to test drive it tomorrow.

The high idle may be due to the primary fuel jets being drilled out but I
didn't touch the primary air jets on top. That may make it overly rich at
idle. The idle fuel adjust seemed to have very little affect. When I looked
down the primaries during idle I can see fuel dripping fairly constantly in
both barrels but it doesn't look very well atomized. Could be just the low
air flow or is it a symptom of not drilling those primary air jets to match.

I also need to hook up the FBVS as that may be causing me some headaches
as well.

I don't think I have any vacuum leaks. I put a vacuum guage on the second
nipple from the front of the carb base gasket and it read a steady 10 and when
I blipped the throttle shot up to 15 or 20 and steadily returned to 10 as it
settled back to idling (at 1500 rpm). I expect if I could get it to idle at 750 rpm
that initial vacuum signal would be zero since thats the one for the advance on
the dizzy ( to my understanding anyway).

Of course I want to take this down to the Mitty this weekend and my wife
thinks I'm crazy. Maybe I am but its fun
