ok my micro drill bits arrived, and i have found what i think is still a std carb.
before i remove the carb from my car i decided to have a practice with the std carb.
what i have found is
air corrector - 1.25mm (125)
main jet - 1.2mm (120)
1st stage - 1mm
2nd stage - 1mm
does this all match up to being a std carb?
