I just finished a complete rebuild of the B30A in my '70 164. Out of curiosity, I did a compression test. I got the exact same results on all cylinders; 80 psi on the first puff, 135 on the fourth. Both the Haynes and Volvo manuals show between 142 and 170 psi for ideal compression on the B30A. Is the discrepancy anything to worry about?
Thanks in advance,
Nick
