Can anybody help, are the powervalves supposed to move up and down when you turn the ignition on? I have a Mc18 RK5, I thought they did so adjusted them and it moved when I switched it on, then you drive down the road, doesn't pull in high revs. Then I stop and rev it and they don't move at all. I have adjusted them again, they don't move when I switch on, but still moves when engine is started and you rev it and it seams to pull up in the high revs ok. What do I need to do?
