I am installing the TBS needles, new idle mix screws and replacing original carb screws with allen heads this weekend. I was looking at the technical help section for "Carburetor Modifications" to see how best to accomplish this task. I noticed that they recommend that the vacuum port hole in the slide should be drilled out to 1/8". Has anyone done this, and if so, what is the advantage of doing this? Also tried to go to Dinqua's Carb Site but said the link was incorrect.
Thanks for any advice,
Alan
