Here's a post from Stephen:
"Blip the throttle to over 3k. Mark the postion that the servo goes to at it's highest (hi point)
Stop the engine and turn the servo to your premarked position.
Set the valves up.
The 12k opening of the valves is the same position as the 3k opening.
Valves need to recessed into the roof by around 0.2mm not flush.
Make sure when blipping the throttle the valves open together after adjustment as cable tension makes a big difference to performance."
So when I goose it over 2500 rpms, the servo should move to the "HI" side or to the "LO" side? (Mine moves to the "LO" side) That's one of my major questions. I can't find a post that says what "LO" and "HI" actually means in "open" or "closed" terms.
