Does anyone remember that old Walter Matthau-Elaine Mays Movie? I can't
think of the title.
He had an incredibly expensive Italian car that was constantly in need of
tweaking.
The standard mechanic line was "Carbon on the valves." It was the only
reason for every imaginable symptom.

Subject: Carbon Build-up
Possibly a stupid question but I'm not proud!
My intake valves are the poster child for running rich - they have a very
heavy carbon buildup (I am in the process of correcting the mixture).
Considering intake porting/polishing that many do I assume this can have a
significant impact on performance (please correct me if I'm wrong).
Will most of the carbon burn off after I run the engine with the proper
fuel mixture? I am considering removing the carbon with a pick and
vacuuming the debris out (while I have the manifolds off) but am concerned
some will get into the cylinder (would this hurt or would it just break
up?).
Does anyone have experience with any gas additives that could remove the
carbon or other alternatives (I would like to put off a rebuild for a few
years)?
Thanks,
Pat
