Not in the good way...
Found my monza running pretty rich today (Holley go figure)
I didn't see any obvious signs of flooding like leaking nozzles so I hooked up the timing light and vacuum gauge.
I found that the timing and gotten pushed to about 16 to 18 degree's advanced. I set that back to 12.
With the Vacuum reading still low at 15 with a big intermittent drop to 10 I decided to bring the idle misture screws in.
I found that I could bring them to nearly closed before the car would stall out. I set them both for barely a half turn out..
I went for a ride, and found a big improvement in takeoff smoothness, and overall power.
Why does my holley want to run with the idle screws turned in so far? Only a half turn out?
