Thanks Don:
I had the same problem with my Clewetts. I had sent them back, and R Clewett gave me a new improved set.

I spoke to a mechanic ( the term mechanic does not nearly describe his skill and expertise), and I richened up my mixture a tad, and backed up the timing 5 degrees. I guess 930's have boost retard on the distributors? My distributor is stock SC.

I neglected to mention I also have water injection, which may explain the lean looking plugs. My AFR's are in the 12's, and I can get into the 10's on boost.
