Try "WinSu" to compare needles.

needle for my 1.75 SU's. This car is completely fresh. At the time being,
the carbs are untouched and have the standard "SM" needles in them. I
understand how these carbs work, but would like to know what some of you
racers may be running or would suggest as a starting point.

undrivable with these needles. In 3rd or 4th gear it can't take but a tiny
bit of throttle and will break up at 4 grand unless you baby it. If you
adjust it too rich at idle it is a bit better under power, but is obviously
no good. I looked at the profiles for the standard rich needles "RH" and I
guess it would be a good start, but I am sure someone out there might get me
closer.

with (I apologize, but the records are not infront of me) 12.5 to 1
compresion and I would say an average race cam.
