What you're seeing would be considered normal ... the APV's are closed until the engine hits a certain RPM. If you want to check your valves, pull the cable ends out of the servo motor housing. Once you have the end of the cable, pull on the exposed wire/barrell end ... you should be able to actually hear your valves click shut when you open them by pulling on the wire. If it pulls extremely difficult, and you don't feel like you're opening the APV, it's time to pull them and get them cleaned.
Mush, the valves ARE supposed to be down, except past a certain RPM. Pretty hard to see them just by looking through the exhaust ports, as they really don't stick down that far. You should be able to FEEL them however, and should be able to press them upwards and then the spring pressure should force them back down in the down or "closed" position. – Roy
