Instead of another compression test, let me suggest a cylinder leakdown test. Following the firing order by looking at the distributor rotor, get each cylinder to the top of its compression stroke, lock the crankshaft by putting the transmission in gear and chocking the wheels front and rear, or putting a couple of pairs of vise grips on the flywheel at the bell housing, put air pressure into the spark plug holes with an adapter made from a spark plug shell and an air hose quick coupler. Listen for air leaks at the carburetor (intake valve) the tailpipe (exhaust valve) and the oil fill cap (piston rings). If you use an air pressure regulator set to 100 PSI with no air flowing, the pressure drop will give you a reading of the percentage of leakdown for each cylinder. I've been using that test for 50+ years. For instance- - - -a pressure reading of 90 PSI on a cylinder with the air pressure in it would indicate a 10% leak rate. Much more accurate than a simple compression test.
