I have this pop in the exhaust at idle and a little shake/miss at constant higher RPMs. I did a compression test today and was wondering if the compression could be causing my symtoms? Engine is a '67 230.
#1 150
#2 155
#3 150
#4 125
#5 145
#6 120
I was going to start with valve adjustment on #4 and #6 first.
Thanks, Clyde
