These were taken a couple days ago before I realized the carb linkage was hanging up. Probably more like 1000 rpm.
Hopefully these links work.
The links are working. Yeah it sounds like 1000+ to me. It sounds pretty smooth, sounds like the ignition system is working pretty well, no big misses. Not a horrible place to start. I'd like to see a video of it idling around 650, or as low as it idles nice, and you putting it into gear w/ your foot on the brake and holding it still. After you get the timing and the dwell set.
If you have the throttle plates all the way closed on the outer carbs at idle, w/their mixture screws turned all the way in and with a smooth idle, can you then kill the engine by turning the mixture screw in on the center carb? Doing that's making sure there aren't any vacuum leaks and the idle circuit is working right on that carb. If you can pass that you should be able to tune it up real nice.
