Ferrari Mailing List: Re: Spark plug reading?

[LarryT (l02turner]

Hi Peter,
   They *do* look good.  My only concern would be driving hard.   50 seems 
a touch lean to me but I'm no expert.

   Perhaps a 20-30 minute run with rpm's covering the range from idle to 
redline.   But be careful with temps, especially at WOT - too lean at full 
throttle can cause high temps on pistons tops.  Would hate to hear you 
burned a hole in a piston.
\
   I know some say when you examine SPs you;re seeing only what happened 
immediatley before the engine was stopped - but I believe it takes a little 
time to get a SP to change color/texture a meaningful amount.

   Good luck -
