afb, avs, t q, metering rods

hi, trying to read numbers on metering rods is a pain, i found , use a magnifying plug reader light, works wonderful can set on rod and read numbers lots easier. just food for thought. also, can read jet sizes also.
I've gotten to where I just say "screw it" and get the dial calipers out. lol For jets, I still struggle. LOL
