Thermo-Quad metering rod measures

I have been using TQs since the late 70s. They do not seem too fussy about exact metering steps.

Not sure what engine you are working on, but even if it was all original, todays fuels are different & the original rods might not be ideal.
#9097 originally uses a 069/50 rod. There are some that are quite close:
- 2110 69/40
- 1938 71/40
- 2159 70/40
- 2211 715/40
