Power valve not opening

Noted.
Anyway since I street-drive the car (and won't be at a strip until I get a trailer, since the nearest one is 90 miles away), just about all the driving is on the primary circuits. I'm too old for the kind of stunts that attract the attention of law enforcement. I'd have to look it up but I seem to recall that the secondaries start to open at 40% throttle?
Tomorrow I'm going on an 80 mile round trip (most of it at 60 mph) so will have run about 8 gal of premium through the carb. No E10 this time.
