I live in south Florida. It is flat as a fritter here, So adjusting the spark advance while driving doesn't seem to be needed. All the way up to start, then halfway down and leave it alone. I put about 150 or more miles a week on my car, and it seems to do fine like this at any speed. Cruise to work at 45. Am I causing any adverse effects to the engine driving like this. I pull the plugs every other week to check, they are a perfect light grey. It gets really hot here, stuck in traffic a lot, never heats up over 170.
