If I have a vacuum leak it is very well hidden I was all over the place with the propane torch and the spray bottle and couldn’t find a dang thing.
Final end of day settings
28 initial as per the markings on the balancer
10 mechanical with homemade advance bushing. Having a hard time verifying that may just put in the 18 and adjust initial because I can’t seem to figure out if the mechanical is working
Advance can plugged into ported vacuum motor didn’t particularly like it on manifold vacuum
And idle screws out 2.75 or so
I didn’t hear any pinging. Maybe you will in the videos?

I know there is definitely still more to do so any help would be appreciated because I still for some reason can’t get the dang thing to do what I wanted.
Weirder than that my dial back reads a different timing setting than the balancer does and I verified the balancer is zeroed at tdc.
The only weird thing I noticed is on compression cyl 1 tdc with the balancer at 0 the rotor button is not pointing at the first plug it’s actually counterclockwise part way to the next which I can only assume is because it wasn’t a fresh distributor install?
Also weird part is I couldn’t use my dial back timing light to check my mechanical timing when I set it to 38 no matter how much I revved I had no marks then when I set it to 28 and revved it actually went to 18 then when I set it to 0 and reved timing didn’t change at all. Once again nothing I’ve found seems to explain that and another example of how nothing seems to do what it’s supposed to.
Just like if I tune the mixture screws for max vacuum they end up about 4 turns out and my idle ends up around 1300 or so with no way to reduce it and it’s obviously running rich at that point because leaving a vacuum completely open raises the idle further. Only around 2.5 turns out does the idle finally falter when a vacuum is unplugged.
Tuning this stuff sucks when you have no idea what you’re doing
