OT - need help with a Jetta

[Larry" <rocco16v@netzero.com (Larry)]

Colin-
  You can be off a tooth either way and the engine will still run smoothly.
 If you've retarded the valve timing, the engine will lose low-end power and
gain on the top-end.  Advanced valve timing will have the opposite effect,
naturally.
