Compression tested today

Not looking very good, but I should have charged up the battery. The mechanic said if the car cranked faster, it should be around 7+

Car is 85k miles and I believe original engine.

Rotor 1
5.8, 6.1, 6.0 @ 204 RPM
6.0, 6.0, 6.3 @ 195 RPM
6.0, 6.1, 6.1 @ 202 RPM
6.1, 6.1, 5.9 @ 200 RPM

Rotor 2
6.2, 6.4, 6.2 @ 214 RPM
6.6, 6.2, 6.6 @ 211 RPM
6.0, 6.4, 6.1 @ 210 RPM
6.5, 6.2, 6.4 @ 210 RPM

'93 shop manual differs from later year manuals.

'93 states 7.0 kgf/cm2 (100psi) minimum at 250 rpm

6.0 kgf/cm2 (85psi) is the '94 shop manual stated minimum

your results look good

The numbers are fairly even, which is a good thing.

if your cranking rpm were at 250 you'd probably be seeing high 6s or low 7s.
