[Mg-mmm] From Andrew Fock on the sparking plug issue

[TATERRY at aol.com]

Hi Terry,

I have used Champion L87Ys for some years in the NA with good  
results... However the engine is old and I do run a hotter plug in one  
cylinder that used to oil a bit. The exact heat is a matter for trial  
and error and it took me a year or so of mucking around with different  
heats before I was happy.
If you think this will be of interest to the list please pass it  
on.... it seems to bounce when I try to post!
