Highland carb rules

[Racing 68]

Who do i contact at highland for tech question on carb.
Or can someone tell me if you are allowed to drill air idle holes in the throttle plates for tuning purposes.

For the last word you would have to talk to Charlie Depew 618-347-2327.

I beleive that is legal because some new carbs come with the plates drilled.
