Tuning help, please

The sound in your video is not pinging. That’s the exhaust banging or something like that. Secondly, to get the timing sorted out you’re going to have to learn how to tune a distributor. You need to know how to limit the mechanical advance before you start adding initial advance in to it. And you should start by verifying that the balancer timing mark is accurate or everything else you do will be worthless.

Thank you. Appreciate the first point, for sure. Helps to narrow focus.

To the second point—it’s a good point. I do need to figure that out too. The points distributor was on the motor when I bought it. Theoretically, it should have been in the ballpark. I verified balancer timing mark already, but plan on checking again, in case I was too distracted by the screaming kid pulling on my leg.
