Just back from a warm-up drive. The car (TR3A) ran exceptionally well. The weather was warm (about 85 degrees) and humid. I've notice this before: the car seems to run very well under such conditions. Is it my imagination, or does this kind of weather make a difference?

hmmm, warm and humid air. The aviation researcher in me says "warm humid air = thin air" (moisture makes the air less dense). Aircraft wings have less "lift" in warm humid air; more lift in cool dry air.

So if you're referring to how the engine was running, running well on warm humid air may indicate you have the mixture set well for "thin air", but not set well for dry (dense) air. Have to balance fuel with air intake.

Just my two cents.

Tom,

"Dry air"... ha, ha. It's been humid or raining here almost every day for most of the spring and early summer. I think we've forgotten what dry (dense) air is. You have given me some good information, however, and when fall arrives and the air is dryer around here, I'll rebalance the fuel and air intake.

Many thanks!
