Triumph twins are clockwise because the point are on the cam. The A65, as you found out, are on the intermediate gear.
Stock timing, if I remember right is 34 degrees BTDC full advance. The retarded timing depends on whether you have ET ignition or battery
type ignition. ET retard is only 10 degrees at the crank. battery
ignition is 24 degrees.
Swapping the coils wires will not fix late timing due to assuming the wrong rotation direction of the point cam.
To get the engine to run with 5 degrees ATDC timing would require opening the throttle from the idle setting since there would not be enough power to get it through the next compression stroke.
EI ignition would only fire at the stock timing if it is just a switch replacement for the points or it was programmed to the same timing. Fully electronic ignition does not use a mechanical advance mechanism. The ones made for these bikes are fairly simple with only RPM as the input. A more advanced ignition would have intake vacuum and temperature, engine temperature, barometric pressure, throttle position and a knock sensor.
Even the simple RPM only type could be better by adding an RPM stabilizer that automatically adjusts the timing at idle.
