Carb has vac secondaries. Suppose to be plug a play for cars under 450hp. I think someone messed with it and returned it.
Would tight valves cause this? I did install the rockers myself and it was my first shot at it.
Vacuum 17-19", the gauge shakes back and forth.
I spray the carb base plate and intake with carb spray and listened for any change in idle. No change.
