I started to hear detonation sound on warm engine. I checked ignition timing and it was about 15 degrees advance. Tried to set it right, but I moved distributor all the way to its limit and only could move ignition half way to where it should be. It is about 7-8 degrees advance now. Detonation got much milder after that, but didn't go away completely. The distributor was replaced 3 years ago and I don't think it is bad again. What else could cause ignition timing shift? sergei
