All engines get carbon deposits in the combustion chamber.

Thanks, Dan
What does this mean? If your question is "Did Porsche build the engines with different comp. ratios for different cylinders in the same engine ?" the answer is no. When new, all the cylinders in a given engine had the same comp. ratio.
