Can anyone that has a set of "non-emission" Dellorto DHLA 40's take a picture (close up like the pic below) of the progression circuit drillings for me? Also if you have jet drills and are able to measure the sizes of them that would be even better!
Non-emission carbs should only have three holes in the progression circuit and the code should be just DHLA40 without a suffix.

I have a pair of DHLA40F's that I paid pocket money for, so I want to see if I can mod them to fix the idle and progression circuit issues associated with them.
Figuring a precision sleeve for the idle air bleed and a precision disc glued into the progression circuit to convert it from 5 holes to three.
