I have a 123 distributor in our 1970 Giulia. It runs reliably and ok. To be honest I am looking for an original distributor. In my memory (it was last knocked out) the engine ran better and somehow more exciting with the original distributor. The 123 is very conservative in terms of advance at higher revs (with the correct map). Even if it sounds far-fetched...the mechanical distributor breathes more life into the engine, like a mechanical watch compared to a quartz watch. The way the engine accelerates and gets up to speed is simply an emotionally closer connection to the machine. But that's a very subjective assessment. Perhaps new contacts or a check of the centrifugal force control or a new coil will work a small miracle.
