I put electronic ignition on mine and I'm glad I did because once set it's something you don't have to worry about, and it takes ignition out of the equation when problem solving. Beware though because not all systems are equal. I got the one from David Silver and if I'm tootling along in traffic with my headlight on then my battery does start discharging, so they do have quite a drain on the system.

Is that correct that Boyers don't use the mechanical advancer?

Some models don't use the mechanical advance.

 yes,the magnets rotor fits directly onto the center of the advance unit,you have to remove the cam,springs and weights to fit,
the electronics do the advance,set ignition at full advance at 4,500 rpm with a strobe,

its worthwhile checking the plug caps and plug leads as a stronger spark will show any faults,especially in the wet.
