As it is not the original engine (later Healey/Sprite, Mini, Metro,
Cooper?), the timing mark may be on the flywheel. Or perhaps the
original pulley was replaced due to damage or not of the proper type for
this application. Was the waterpump and/or dynamo-alternator changed?
If you cannot find any mark, just measure nr. 1 piston TDC accurately
and make the mark yourself .
One way of doing that is to make an adaptor from a sparkplug to blow
bubbles from soapy water. Inserta few drops of heavy oil on the piston
to create a really good seal. Put the piston in TDC as well as you can,
fit the adaptor, stretch a film of soapy water accross the opening and
find the position the bubble is at its biggest.
That is TDC.
It does not sound like very sophisticated technology but it works, you
do not need special tools apart from making up an adaptor from an old
sparkplug and it is extremely accurate.
