Umm, yes to a point. I suspect that you may be able to find a setting that
will start and keep running, but do remember that your motor is rather more
than "slightly" more modern than a model T engine. A model T would do in
revs/min what yours would do in revs/sec - well maybe not quite that ratio,
but not that far off it.

Well I was thinking in terms of electronic adjustment of the advance being
done automatically as the engine started. :)

Bear in mind that the fuel burn time in the cylinder may be a significantly
higher percentage of the rotational angle than the fixed manual adjustment
on the model T engine mentioned above. This may mean that you need a more
pro-active means of adjusting the advance as the motor starts than a manual
adjustment.
