Not a hundred-series, but put one on our 3000 about 5 yrs ago. Haven't touched it since, always good spark. I spent many hrs on many engines in my early days setting gaps, cleaning & changing points, etc., so have really liked it. Planning to put it on the 3400 we got last spring.
Not sure how good it would be if the distributor is worn and has a lot of slop (gap to pickup sensor would drift).
Others on this board still like points a lot, so look thru the archives and read their posts, too.
