wow, now that's interesting. I'm now exploring something that is actually a mystery to me, BUT..... Using the ol' common sense, we can venture into a few possibilities. 1)Warm weather= warmer engine. Timing changes. 2) Warm weather= gasoline vapors in the line. pressure settings change. Mind you , these are wild a** guesses. What do you think?
I hope someone gives us a better response than mine.- I'd like to learn something myself.
