I've changed the jets on the carb but waiting til I get timing set before completely tuning it. If I set 16 initial/36 total, it runs fine. But it idles better -- and has more vacuum obviously -- at 24 initial. Like I said before, the motor likes a lot of initial. When I had my old cam (.509 Purple cam), I once timed motor by ear using a vacuum gauge. I got smoothest idle and highest vacuum and I looked and was at 40 initial. That wouldn't work. I'd like to run vacuum advance, but if I cant it's no big deal. As for my recent post, how do I adjust can based on my timing reading when I use mityvac on advance? Do I check timing at 2,600? Thanks
