Initial timing

I think I'm making things progressively worse lol. Vac at idle is now 4". Gotta check carb. I have a kit for the Eddy 1405 coming, so the plan is to leave Carter on until I get Eddy back together. Also have the 5/16 spacer but waiting to install that with Eddy.
I know when I hooked Mity Vac up to Va. The arm movement started at approx 7-8" of hg which I believe is good.
My VA is adjustable, but I've learned that the "adjustable" part is the "when" of it. NOT the amount of vac adv.
Thanks all, back to work over next few days, so hopefully get Eddy redone when kit arrives....
Does it really have 2" of vacuum at idle, or did I misread that?

I just watched your videos. Sure does seem like the can is putting in mega amount of advance.

Check that you dont have exh valves too tight/ hung open.
Find a port that's fed like the pcv , tee off that if need be.
