[Mgs] Pertronix Flame Thrower distributor

[Henri Lefebvre]

I recently installed a Pertronix Flame Thrower distributor in my 71 MGB GT.

For proper ignition timing purposes, would anyone be abIe to provide
the following information:

1 - Distributor mechanical advance of this distributor:    10 degrees?
or 20 degrees? or other?

2 - Vacuum advance:    connection to manifold? or carburettor?

3 - Recommended Ignition Timing, based on the above and engine year?

All and any information and recommendations welcomed.

Thank you,

Henri
