Thermoquad low vacuum readings

Installed .110” jets to help with light throttle lean condition and so I didn’t have to screw the rod adjust so high trying to compensate.

I decided a part of the problem was the “Industrial” carbs rods had 67/57/45 rods when stock 340 rods are 67/52/45 or so.
So I checked my 9000 series parts carbs for rods. Came up with 67/57/54 emissions rods and modified them to 67/52/42. I’ll test all this later.

I’ll start a separate thread to show how I made my own rod sizes in case others are interested.
