UNF or BSF Threads for A-series 948 engine

Posted by Keith Lawrence (PUT - 690) on January 03, 2003 at 08:28:55:

I'm confused?...

I'ld like to buy a set of taps and dies to do some light work of PUT-690s carbs and exhaust. Are BSF threads used? I've read up and can't get a straight answer. Any help on what sizes would be needed for the engine would be great - if not needed, I don't want to buy a complete set.
THANKS Keith

Happy new year!!
