Thanks Adrian, That sounds like a plausible explanation. I am planning to
put a Spitfire head on it, so I will probably wait and have that head redone
with the unleaded conversion(although I have never held much stock in the
unleaded valve recession theory)
I am planning on doing some "running exercises" today, so hopefully it will
clear up as suggested.
An aside to all the listers who have responded so far- THANKS! I am still
interested in more ideas, suggestions, etc.
