Yes they do Bernie, a stock 3B's maximum total advance is 12 degree BTDC, 
not corrected by intake temperature compensation which range or temp range 
I won't mention here. On the 360+ 3Bs that I've tuned so far, total advance 
is increased to about 26 degree BTDC, uncorrected too. No further retard 
over stock values BTW.

I quite frankly don't know, it has never happened to me, so I suppose that 
if it's done properly (I'm not saying I've really done it properly but it's 
been 30.000 miles that those motors have been running strong with no 
damage) it can't happen, at least not if everything else on the motor is ok...

HTH,

Mihnea
