Thanks for all your replies. I have yet to consider what everyone said, but I have an update: I filled up with 91 gas and used a Lucas 3x octane booster. After that I retarded the timing to 13 advanced. It runs much better now, with pinging only if I open the secondary barrels on the carb. I'll keep experimenting.
