Check compression pressure with engine at normal operating temperature, all spark plugs removed, electrical lead to anti-dieseling solenoid disconnected, choke and throttle valves wide open and engine at cranking speed.
Crank engine at least 6 revolutions to determine engine compression. Lowest cylinder pressure should be at least 80% that of the highest cylinder pressure.
| Compression Ratio | Compression Pressure |
|---|---|
| 8.5:1 | 128-171 psi (9.0-12.0 kg/cm 2 ) |
