Sounds good Clark, I am home now, we have an engagement at 3 that requires a shower first, wife would kill me in my sleep if I miss either the party or the shower. (That sounds way more fun than what I meant LOL)
Should be around next weekend too if today doesn't work.
I will offer a couple observations if you decide to go at it this afternoon.
1 - Point gap and coil check - Make sure your point gap is dead on. Loosen the distributor to get it perfectly on the point cam, then adjust and make sure the points are clean. Also, make sure your coil is wired up the right way. "Dist" or "-" goes to point side. I have seen a couple over the years that guys get them backwards by accident.
2 - Set initial timing higher - 10 degrees at 1300-1400 is likely not enough timing especially at that RPM. Get it at 12-14 at a 750 or so idle, vacuum disconnected and plugged to distributor and make sure ported vacuum is dead. I have a hunch you have the primaries open too much, see below.
3 - If ported vacuum is not dead at whatever idle you are at, pull the carb and close the primaries and open the secondaries an equal amount. Then reinstall and readjust. It might take a few times, you are looking for about .020 of transition slot up front and a nice 750-ish idle. Once you get close and it idles, set timing, resent a/f mixture to highest idle then lower to 750 again.
Beyond that it'll take some thinking and listening.
