Could someone please let me have the information? I've borrowed a timing light and want to get this all correct before I start on the carb.
 
Depends on the distributor. There should be some letters on the side that show which one it is.

ST: 5 to 7 degrees BTDC (9mm to 11mm before TDC mark)
R252: 1 degree BTDC to 1 degree ATDC (1.8mm either side of TDC mark).
R284: 5 to 7 degrees BTDC (9mm to 11mm before TDC mark)

Glossery - BTDC = before top dead centre. A = after.

Do you have a Haynes manual? They are worthwhile. About £25 from Haynes or dead cheap from eBay.
