Hook up a compression gauge on each cylinder in turn and spin the motor.the coil is a single one- standard classic SE car with supersprint engine
I wouldn't be too worried about the size of the numbers, but ideally all cylinders should produce a similar number.
If one cylinder is markedly down on the other three, you can do a "wet" test by adding some oil to the errant cylinder and re-testing. If the number improves, then the problem is rings/bore. If it doesn't improve then the problem is likely to be valve-related or head gasket related.
