I said I was going to try most or all of the suggestions as part of a systematic tuning process, and I haven't ignored yours. I've already gone down two steps on the jets and don't think I will mess with them further until I get the other settings in range. 74's are close - at least, there's no sign of them being over-rich.
Ditto for the power valve, which has more effect on upper-end power than the off-idle and low end power I'm working with right now. It probably could benefit from a change, but has to wait until I can see how the secondaries and upper power are working. Without the secondary spring set, I can't even get into the secondaries - the stock spring is much too strong for this engine.
Opening up the idle mix helped, but only to a degree, and I think the baseline is messed up by the air cleaner change, so I have to start over there. The distributor recurve doesn't feel quite right but I'll leave it for now and go back to less initial only if I'm still seeing detonation after the carb adjustments.
Since I've tweaked the idle mix and timing and still have some bog coming off idle, I am back to suspecting the accelerator pump tuning and possibly the stalled secondaries. When and if my parts ever come, I'll be able to test my theory. If the rain stops.
