well, i hooked up my timing light to the battery on my harley, hooked the lead up to #1 cylinder....i put a little white paint on rotor factory 38 degree mark, then put another mark .075" to the right (retarded) of the factory mark, which should be about 35 degress BTDC.....started up the Triumph, revved it up til advance peaked out, and BLAMMO, right on the 35 degree mark! so just for grins, i put lead on #2 cylinder, and fired it up again, and danged if it wasn't **** on 35 degrees BTDC also!!! ( i know the only way to adjust timing on #2 cylinder with the 4CA points is to adjust #2 set of points, but fortunately i won't need to do that...i think i'll leave her just where she is!!!
btw, a friend of mine came over a couple of weeks ago and set points gap and then timing (static) using his "old school" method. (i'm not even sure what he was doing actually, but it did involve a meter stick down in the plug hole.....after he set it, the bike started and ran like a champ, but i wanted to learn how to use the strobe light on it so i could check it myself in the future. he was actually shooting for 38 degrees BTDC, but missed by a couple of degrees in my favor, as i was wanting to set it at 35 degrees! life is good.....
many thanks to Redmoggy and Mr Pete for walking me through this!!
