Oof. Spec is 195, I think.

EDIT: manual says...

Standard compression pressure is 1400 kPa (199 psi) at 250 RPM

Minimum allowable compression pressure is 1100 kPa (156.4 psi) at 250 RPM

Evaluate the compression tests:

- Piston rings faulty: if the cylinder compression is low on the first stroke and tends to increase on the following strokes (but does not reach the compression standard), the probable cause is rings. The addition of oil should improve the compression considerably.

- Valves faulty: if the cylinder compression is low in the first stroke and does not increase on following strokes, the probable cause is valves. The addition of oil does not significantly improve the compression pressure.
Does it burn oil?
