3.9 rover Timming settings?
Moderator: Micka
For Disco motor
2 degrees low comp initial setting. Should run ok at this.
6 degrees on aussie ULP
6 to 10 on lpg
Will supposedly make more torque at 2 after tdc but economy suffers.
Ensure you do a TDC check as many markings are known to be out.
ie No 1 at tdc measured at piston thru plug hole to timing mark tdc.
Airflow may be too lean. Adj with allen key on side for about 2% co.
Out is lean, in (clockwise) is richer.
