Adding vacuum ports to Bing 64/32

[Kriegmeister]

I've got 6432/9 & 10 mounted to my '71 R75, but they don't have vacuum ports - either on the side or underneath. I know I can get them from Bing and others. Is installing them simply a question of drilling into the carbs on the diamond shaped surface opposite the butterfly pivot? There are two indents already present that look like they would fit the bill, and would ease drilling too.

Thanks in advance,

Matt

Probably...that's where they are on my 64/32 -19/-20s. Why not just buy the kit and follow the instructions...I suspect they might vary by carb number.

We found them to be a big waste of time and not at all accurate. it was faster and better to tune by ear.
