Throttle shaft vacuum leak on new Proform carb!

Obviously from the pics, I have a Lokar kd cable. When I put the car back together after head porting, I had switched to a shorter kd lever on the transmission.
Apparently I set it up too tight due to some bad info I read somewhere about having it set where the lever was partially engaged. The more I thought about the factory rod setup, the less sense that info made.
I went back to the longer lever and got the kd setup where there is no tension at idle. The Proform is doing better now. Hopefully I didn't do too much damage in a few drives. Live and learn. I will also look for a better throttle return spring setup.

I would still like to fix my Holley, though...
