I never did say it influence ignition timing I just asked if it was the same as I am no expert on these things I just know my own Norton, I static time my Joe Hunt at 28 deg BTDC as usual, once the bike is running I will advance it, if there is no kick back, once I get a little kick back I slightly retard the timing till no kick back when starting it, I have never used a timing light on my Norton in 48+ years of owning it (don't even own a timing light) and doing it my way works for me.
Setting my timing the way I do it has always started my motor with one kick every time, to me a big spark plays a big part in that, yes technique does play a big part (been doing it for 48+ years so must know what I am doing), I must have it right as I never get any kick back and as I have always said the first kick of the day will always be a full swing on the kicker, but once it has fired up I can do lazy kicks and it will always fire up 1/2 way through the swing of the kicker at full advance and in 13+ years only kick back was when first setting/tuning the JH ignition, hasn't kicked back since and with near 45K miles with the Joe Hunt on my Norton.
My Norton will putter around at low rev when riding the suburbs and crack open the throttle it will get up and go with out any hesitation at all right through the rev range, no misfire, just get up and go, with the work done to my motor it will rev very freely, but I no need to rev it up too 8K RPMs and beyond, no need to throw a conrod or anything, I look after my motor and as I have said in my other replies after 48+ years of owning my Norton since new with the Joe Hunt it's running the best it ever has since installing it, so to me that big spark has made a bit improvement to my Norton's running, but tuning the carbs also plays a bit part it's not only ignition timing but carbs as well they both work together for an easy start and running motor.
