Hello people. My 82 cx500 is a little confusing….the left cylinder is running at 190 lbs compared to 155 on the right . Any ideas on why the one it’s so abnormally high?
Yes, many times.Have you checked that your gauge is giving true readings?
I’m inclined to think that’s it. I may try introducing a carbon removing product through the sync port.Rich mixture or bad valve stem seals cause carbon buildup. Carbon buildup increases compression by displacement.
