Finally got around to changing my plugs and testing the compression in my '80 Fairmont w/ 200 six.
1 130 (143 after adding oil)
2 150
3 130 (152 after oil)
4 155
5 145
6 150
Also plugs 3-6 were really black from running rich lately (i assume) from adding a 2bbl and getting it running right. The car sat for about 4 years but I've been driving it occasionally for a few months. New plugs helped with some midrange drivability issues and I just sorted out a malfunctioning choke problem.
I was a little dissappointed to see some low numbers. I plan on adding some oil to my gas from now on to help the rings out some.
Should I be concerned about these numbers? I feel like theyre almost close enough to not be a huge ploblem? Would like to put a t5 in it and a header or a least delete the cat.
