Lol. The kit is just a adjustable vacuum advance kit from MSD. Base timing is with the vacuum advance disconnected, I plug it in, it goes to 24 which I can adjust with the adjustable vacuum canister. my biggest thing is with the mechanical weights at the end. I can swap out springs to speed it up or slow it down but how do you actually change the timing to advance it more or retard it more, If I turn the distributor to adjust it, it throws the base timing out of whack.Another thing I do not quite understand is manifold vacuum versus ported vacuum.If I use ported vacuum, wouldn't that completely make the mechanical weights obsolete because the vacuum increases as you rev the engine up therefore advancing the timing?. I feel like I'm 15 again lol
