Hi Eric-
Yellow spark is 'weak' spark; BLUE is where it's at, baby, YEAH! Not that
that's necessarily the problem - the low spark could be from the load from
the starter.
Others have suggested the carbs, and that's a good place to start. Turn both
adjustment knobs all the way in, then back out one turn. Jack the idle screws
open a ways, and have at it. Don't use the choke until you've cranked it
quite a bit; I've found that Datsun 4's don't need a lot of choking.
It would also help to set your timing to 0 BTDC, or maybe even a degree or two
AFTER TDC.
