Model number for lucas distributor as fitted to mark 2 zephyr?

Hi

Assuming these are for a six-cylinder engine, the basic numbers, stamped on the body just below the cap, are:

40546B for the high-compression head (7.8:1) - low tension terminal normally has a red washer

40545A for the low-compression head (6.9:1) - low tension terminal normally has a green washer

For Australian models the above numbers may become:

DM2-40546B for the high-compression head (7.8:1)

DM6-40545A for the low-compression head (6.9:1)

When points are fully open, loosen the two main screws to get close to initial setting (below), then perform fine setting of points by turning the small eccentric screw in the adjustable contact plate. Tighten the main screws and re-check setting.

Set points gap to 0.012 inch - if this promotes difficult starting increase gap to 0.013 inch and re-try. If this is unsuccessful use the factory 0.014 inch setting.

The knurled adjustment wheel minutely adjusts timing to suit different grades of fuel.

Hope this helps

Cheers
