IDLE MIXTURE SCREWS BBD 2BBL CARB:/6 OR 318V8
The Idle mixture screws I have measure:
4.78mm (0.188") OD (across the threaded section)
35.32mm (1.391") overall length
(for reference not exact values)
17.25mm (.679") total length of the threaded section (under head of screw to end of threads)
13.48mm (.531") needle section (from thread to tip)
4.59mm (.181) head thickness
3.51mm (0.014")OD at widest part of taper
0.085mm (.033") OD at narrowest part of taper
looks like 32 threads per inch
They appear to be brass (color in photo makes them look steel)
