Hello, I just wanted share my experience on this.
I was doing a basic cleaning of a Holley
4150 750 Double pumper.
In doing the cleaning process I sprayed carb cleaner in all the ports on the meter blocks .
I see carb spray bubbling out pas the mixture needles on one of the four corners idle screws .
I have never changed the small needle gaskets on the outside of the blocks before .
Kind of over looked them.
Don't do this it affects your idle .
They are available separately on
26-110-10.
Lessons learned.
