I noticed this 'port' open, the hole in the carb body, beside the mixture screw..I was trying to figure why the mixture screw didn't do anything. I'm assuming I have to make a little plug to block this, without messing with the little holes I the bottom. There appears to be a shoulder in the hole for that reason.

I wonder how many years I was driving it like this, cursing why it idle funny. It only took 50 years of ownership to get smart enough to fix it.
