Then you probably don't have the 009 -- that's a mechanical only distributor. You may have an svda (see last link on H30/31 with SVDA vs a vacuum only disti) Does it have a number on the side? Pics?
For a 34pict3 the mod is to solder the hole in the throttle plate (and actually this was what I was thinking of when I made the comment above).
For the H30/31, some suggest increasing the drilling on the accelerator pump jet.
But, most would suggest not modifying the carb but going away from the 009s.
