"In all the 6v to 12v conversions I"ve seen, and done, the only thing needed is a voltage reducer for the spark plugs."
Yep, that"ll help!
Lest someone be offended, rest assured I am laughing WITH them, not AT THEM. For those of us that work with this stuff day in and day out, sometimes it is almost UNFATHOMABLE the ignorance some folks who have a "REAL" life have of basic electricity and ignition systems!
And, likewise, some of those folks would find my ignorance of things they take for granted in their everyday jobs UNFATHOMABLE!
