Just finished the compression test. Here's the results:
Cyl 1: 130 PSI
Cyl 2: 140 PSI
Cyl 3: 130 PSI
Cyl 4: 135 PSI
Cyl 5: 135 PSI
Cyl 6: 130 PSI
Cyl 7: 130 PSI
Cyl 8: 135 PSI
So that falls within range from highest to lowest.
I installed a new set of plugs. The original R45S set looked nicely worn. From the old receipts, I think they had 50,000 miles on them and were due for a change.
I also swapped out the distributor cap since I had an new AC/Delco one on the shelf. The old one was a bit carbon-ey inside. The timing looked good as-is, at 12 degrees BTDC. She starts on the first crank. Rather impressive!
