Maestro 1.3 timing

[pister]

There have been a similar thread not long ago, but I have a question! I have acquired a Ledbury Maestro and am wondering if these cars are equipped with low compression engines? What is the correct setting for the timing?:confused:

To tell if you have a high or low compression engine check the engine number prefix, 12H indicates high compression, 12L low compression.

Ignition timing settings are

low compression 8 degrees BTDC @ 1500rpm vacuum pipe disconnected and plugged.

high compression 14 degrees BTDC @ 1500rpm vacuum pipe disconnected and plugged.

(9 times out of ten on a HC engine with todays fuel the timing will have to be set to 12 degrees @ 1500rpm vacuum pipe disconnected and plugged to eliminate pinking)
